Compound Structure Image

This space displays an image of the chemical structure in 2D Rendering.

You can copy a chemical structure from this page, and then paste the image in the Structure Drawing box on the Compound Search page in order to create and modify new chemical structures.

Right-click inside the structure to bring up a contextual menu.
Select the Copy option.
Paste the copied structure in the Structure Drawing box on the search page in order to create a new chemical search query.

index

Preferred Name

This line displays the preferred name (also known as the compound name) of the compound. The name is generally duplicated in the Synonym Name(s) field.

index

Synonym Name(s)

This line displays synonyms of the compound. Note that the preferred name also appears in the list.

index

Systematic Name

This line displays a descriptive systematic chemical name for the compound.

index

Substance Descriptors

This line displays substance descriptors, which are keywords that relate to classes of compounds. They are designed for retrieving groups of substances that are difficult to retrieve using a compound structure query.

index

Structure Description

This line displays a structure description of the compound, if available. It generally exists if there is no compound image.

index

Standardized Molecular Formula

This line displays the standardized molecular formula, which consists of several molecular formula fragments. The number of occurrences of each fragment is shown, delimited by the * character.

index

Molecular Formula

This line displays a Derwent applied molecular formula, which may differ in stoichiometry from a formula calculated from the structure. It contains the molecular formula for each fragment in the structure, separated by dots. It may also contain words when the structure is not known.

index

Molecular Weight

This line displays the molecular weight of the compound structure.

index

Derwent Chemistry Resource Number

This line displays the Derwent Chemistry Resource Number, a unique identifier for specific chemical compounds.

The structure of the DCR Number is NNNNNNNN-NN-NN-NN, where:

"NNNNNNNN"	1 to 8-digit sequential number
"NN"	first suffix for stereoisomers (number from 1-99)
"NN"	second suffix for salts (number from 1-99)
"NN"	third suffix to deal with other cases such as physical forms, isotopes, tautomers, etc., (number from 1-99)
