Entries are organised as follows:
Duplicate Names
In cases where two or more compounds share the same name the duplicate name is followed by the double dagger symbol ‡.
Naming Systems
Compound names are followed by the naming system where appropriate.
The main entry diagram appears towards the top of the entry. This diagram shows any relevant stereochemistry and numbering systems.
The stereochemistry will usually refer to the first variant in the entry. However if the compound is a drug or natural product it may refer to the pharmacologically active isomer or to the naturally occurring form.
Variants
Different forms of the entry compound. e.g. (R)-form or Pyranose-form etc.
Derivative
Common modifications to the entry compound. e.g. Me ester
The entry compound is usually the most fundamental parent compound (e.g. carboxylic acid) regardless of whether or not it is a known compound.
Physical properties and other data, including CAS Numbers (where available) and InChi/InChi keys are displayed under each variant and derivative.
Structures for variants and important derivatives can displayed by clicking
on the Structure icon to the right of the variant/derivative.
These structures are derived from a 2-D connection table
and do not contain stereochemical information.
References for all known compounds in an entry are presented at the bottom of the entry.
Each reference is followed by a reference tag, indicating to which variant/derivative the reference belongs and the type of information contained in the article. For a list of the most common abbreviations used in reference tags click here.
Reference tag organisation:
Properties at the beginning of the reference tag refer to the entry compound, whereas properties for derivatives follow the derivative descriptor.
e.g.
(synth; pmr, cmr, ms, R-form, Ac) indicates that the article contains synthesis, pmr, cmr, and ms data for the entry compound, as well as information on the R-form acetate derivative, whereas:
(R-form, Ac, pmr, cmr, ms) indicates that the article contains pmr, cmr and ms data for the R-form acetate derivative, but no information on the entry compound.
Cross references to related compounds are indicated by a blue hyperlink consisting of the name of the target entry. Simply position your mouse pointer over this and the cursor will change to a hand shape. Click once and you will be taken to the cross referenced entry.
