Carboxylic Acids and their Derivatives

Hydroxy, Alkoxy and Oxo Acids Rule C-415

415.1 (Partly alternative to Rules C-416.1 and C-416.2) - The names of carboxylic acids containing an aldehydic and/or one or more ketonic groups in the principal chain or parent ring system are generally derived from the names of the corresponding simple carboxylic acids by adding prefixes "oxo-", "dioxo-", etc. (see Rule C-316.2).

Examples to Rule C-415.1

(see also Rule C-416.1)

415.2 - The prefixes "oxo-', "dioxo-'', etc., are used also in conjunctive names to indicate substitution.

Examples to Rule C-415.2

415.3 - When a carbonyl group is at the point of attachment of a side chain in a carboxylic acid, the name of the side chain is the name of the acyl radical RCO- (including formyl HCO-).

Examples to Rule C-415.3

415.4 - When a carbonyl group is present in a side chain but not at either end thereof an "oxoalkyl'' prefix is used.

Example to Rule C-415.4

415.5 - When ring systems are united by a carbonyl group only and one of these ring systems carries a carboxyl group, the compound is named as an acid containing an acyl substituent (see Rules C-403.2 andC-404).
