DEFINITION

Classification: 562/512

Acyclic:

(under subclass 400) Compounds wherein the acid contains no carbocyclic nucleus.

(1) Note. Cyclic polyvalent metal salts of acyclic polycarboxylic acids are considered acyclic for this classification.

(2) Note. This subclass contains, for example: [figure] [figure]
