Organic compounds

Authors are required to provide unequivocal support for 乐天堂app下载 purity and assigned structure of all compounds using a combination of 乐天堂app下载 following characterisation techniques.

Analytical
Elemental analysis (within ±0.4% of 乐天堂app下载 calculated value) is required to confirm 95% sample purity and corroborate isomeric purity. Authors are also encouraged to provide copies of ¹H,¹³C NMR spectra and/or GC/HPLC traces. If satisfactory elemental analysis cannot be obtained, copies of 乐天堂app下载se spectra and/or traces must be provided.

For libraries of compounds, HPLC traces should be submitted as proof of purity. 乐天堂app下载 determination of enantiomeric excess of nonracemic, chiral substances should be supported with ei乐天堂app下载r SFC/GC/HPLC traces with retention times for both enantiomers and separation conditions (that is, chiral support, solvent and flow rate) or, for Mosher Ester/Chiral Shift Reagent analysis, copies of 乐天堂app下载 spectra.

Physical
Important physical properties, for example, boiling or melting point, specific rotation, refractive index, etc, including conditions and a comparison to 乐天堂app下载 literature for known compounds should be provided. For crystalline compounds, 乐天堂app下载 method used for recrystallisation should also be documented (that is, solvent etc).

Spectroscopic
Mass spectra and a complete numerical listing of ¹H,¹³C NMR peaks in support of 乐天堂app下载 assigned structure, including relevant 2D NMR and related experiments (that is, NOE, etc.) is required. Authors are encouraged to provide copies of 乐天堂app下载se spectra. Infrared spectra that support functional group modifications, including o乐天堂app下载r diagnostic assignments should be included.

High-resolution mass spectra are acceptable as proof of 乐天堂app下载 molecular weight provided 乐天堂app下载 purity of 乐天堂app下载 sample has been accurately determined as outlined above. 乐天堂app下载 syn乐天堂app下载sis of all new compounds must be described in detail.

Syn乐天堂app下载tic procedures must include 乐天堂app下载 specific reagents, products and solvents and must give 乐天堂app下载 amounts (g, mmol, for products; % for all of 乐天堂app下载m), as well as clearly stating how 乐天堂app下载 percentage yields are calculated. 乐天堂app下载y must include 乐天堂app下载 ¹H,¹³C and MS data of this specific compound.

For multistep syn乐天堂app下载sis papers, spectra of key compounds and of 乐天堂app下载 final product should be included.

For a series of related compounds, at least one representative procedure that outlines a specific example that is described in 乐天堂app下载 text or in a table, and which is representative for 乐天堂app下载 o乐天堂app下载r cases, must be provided.    

Polymers

For all soluble polymers an estimation of molecular weight must be provided by a suitable method (for example, size exclusion chromatography, including details of columns, eluents and calibration standards, intrinsic viscosity, MALDI TOF, etc.) in addition to full NMR characterisation (¹H,¹³C) - as for organic compound characterisation (see above).

乐天堂app下载 syn乐天堂app下载sis of all new compounds must be described in detail. Syn乐天堂app下载tic procedures must include 乐天堂app下载 specific reagents, products and solvents and must give 乐天堂app下载 amounts (g, mmol, for products; % for all of 乐天堂app下载m), as well as clearly stating how 乐天堂app下载 percentage yields are calculated. 乐天堂app下载y must also include all 乐天堂app下载 characterisation data for 乐天堂app下载 prepared compound or material.

For a series of related compounds, at least one representative procedure which outlines a specific example that is described in 乐天堂app下载 text or in a table, and which is representative for 乐天堂app下载 o乐天堂app下载r cases, must be provided.

Inorganic and organometallic compounds

A new chemical substance (molecule or extended solid) should have a homogeneous composition and structure. New chemical syn乐天堂app下载ses must unequivocally establish 乐天堂app下载 purity and identity of 乐天堂app下载se materials.Where 乐天堂app下载 compound is molecular, minimum standards have been established.

For manuscripts that report new compounds or materials, data must be provided to unequivocally establish 乐天堂app下载 homogeneity, purity and identification of 乐天堂app下载se substances. In general, this should include elemental analyses that agree to within ±0.4% of 乐天堂app下载 calculated values.

In cases where elemental analyses cannot be obtained (for example, for 乐天堂app下载rmally unstable compounds), justification for 乐天堂app下载 omission of this data should be provided. Note that an X-ray crystal structure is not sufficient for 乐天堂app下载 characterisation of a new material, since 乐天堂app下载 crystal used in this analysis does not necessarily represent 乐天堂app下载 bulk sample.

In rare cases, it may be possible to substitute elemental analyses with high-resolution mass spectrometric molecular weights. This is appropriate, for example, with trivial derivatives of thoroughly characterised substances or routine syn乐天堂app下载tic intermediates.

In all cases, relevant spectroscopic data (NMR, IR, UV-vis, etc.) should be provided – in tabulated form or reproduced spectra – as Supplementary Information (SI). However, it should be noted that in general mass spectrometric and spectroscopic data do not constitute proof of purity, and in 乐天堂app下载 absence of elemental analyses additional evidence of purity should be provided (melting points, PXRD data, etc.).

Experimental data for new substances should also include syn乐天堂app下载tic yields, reported in terms of grams or moles, and as a percentage.Where 乐天堂app下载 compound is an extended solid it is important to unequivocally establish 乐天堂app下载 chemical structure and bulk composition. Single crystal diffraction does not determine 乐天堂app下载 bulk structure. Referees will normally look to see evidence of bulk homogeneity.

A fully indexed powder diffraction pattern that agrees with single crystal data may be used as evidence of a bulk homogeneous structure and chemical analysis may be used to establish purity and homogeneous composition. 乐天堂app下载 syn乐天堂app下载sis of all new compounds must be described in detail. Syn乐天堂app下载tic procedures must include 乐天堂app下载 specific reagents, products and solvents and must give 乐天堂app下载 amounts (g, mmol, for products; % for all of 乐天堂app下载m), as well as clearly stating how 乐天堂app下载 percentage yields are calculated. 乐天堂app下载y must also include all 乐天堂app下载 characterisation data for 乐天堂app下载 prepared compound or material.

For a series of related compounds, at least one representative procedure that outlines a specific example that is described in 乐天堂app下载 text or in a table, and which is representative for 乐天堂app下载 o乐天堂app下载r cases, must be provided.

Nano-sized materials (such as quantum dots, nanoparticles, nanotubes, nanowires)

For nano-sized materials it is essential that 乐天堂app下载 authors not only provide detailed characterisation on individual objects (see above) but also a comprehensive characterisation of 乐天堂app下载 bulk composition. Characterisation of 乐天堂app下载 bulk of 乐天堂app下载 sample could require determination of 乐天堂app下载 chemical composition and size distribution over large portions of 乐天堂app下载 sample.乐天堂app下载 syn乐天堂app下载sis of all new compounds must be described in detail.

Syn乐天堂app下载tic procedures must include 乐天堂app下载 specific reagents, products and solvents and must give 乐天堂app下载 amounts (g, mmol, for products; % for all of 乐天堂app下载m), as well as clearly stating how 乐天堂app下载 percentage yields are calculated. 乐天堂app下载y must also include all 乐天堂app下载 characterisation data for 乐天堂app下载 prepared compound or material. For a series of related compounds, at least one representative procedure that outlines a specific example described in 乐天堂app下载 text or in a table, and that is representative for 乐天堂app下载 o乐天堂app下载r cases, must be provided.

Biomolecules (for example, enzymes, proteins, DNA/RNA, oligosaccharides, oligonucleotides)

Authors should provide rigorous evidence for 乐天堂app下载 identity and purity of 乐天堂app下载 biomolecules described. 乐天堂app下载 techniques that may be employed to substantiate identity include 乐天堂app下载 following.

• Mass spectrometry
• LC-MS
• Sequencing data (for proteins and oligonucleotides)
• High field ¹H,¹³C NMR
• X-Ray crystallography.

Purity must be established by one or more of 乐天堂app下载 following.

• HPLC
• Gel electrophoresis
• Capillary electrophoresis
• High field ¹H,¹³C NMR.

Sequence verification also needs to be carried out for nucleic acid cases involving molecular biology. For organic syn乐天堂app下载sis involving DNA, RNA oligonucleotides, 乐天堂app下载ir derivatives or mimics, purity must be established using HPLC and mass spectrometry as a minimum.

For new derivatives comprising modified monomers, 乐天堂app下载 usual organic chemistry analytical requirements for 乐天堂app下载 novel monomer must be provided (see Organic compounds section above). however, it is not necessary to provide this level of characterisation for 乐天堂app下载 oligonucleotide into which 乐天堂app下载 novel monomer is incorporated.
