Standard Classification System for Chemicals According to Functional Groups

SCOPE
1.1 This standard is to provide a classification system for chemical compounds, primarily by functional groups with a three-digit numerical code. Polyfunctional compounds can be cross-indexed by use of as many codes as there are functional groups.

Standard Classification System for
Chemicals According to Functional Groups
This standard is issued under the fixed designation F 1186; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
