Carboxylic Acids and their Derivatives
Simple Carboxylic Acids Rule C-402 402.1 - If an unbranched chain is linked directly to more than two carboxyl groups, these carboxyl groups are named from the hydrocarbon
by substitutive use of the suffix "-tricarboxylic acid", etc. (compare Rule C-401.2). The principal chain should be linked directly to as many carboxyl groups as possible. The
carboxyl groups which are not directly linked to the principal chain are expressed by "carboxyalkyl-" prefixes.
See Recommendations'93 R-5.7.1
Examples to Rule C-402.1
In the last example, the principal chain is not the longest, but is the one directly linked to the greatest number of carboxyl groups.
