Collidinic acid[1][2] (pyridine-2,4,6-tricarboxylic acid) is an organic compound that belongs to the heterocycles (more precisely the heteroaromatics). It belongs to the group of pyridinetricarboxylic acids and consists of a pyridine ring which carries three carboxy groups in the 2-, 4- and 6-positions. The name is derived from 2,4,6-collidine (2,4,6-trimethylpyridine).

Preparation

The compound can be obtained from the oxidation of 2,4,6-collidine by potassium permanganate.[3]

Uses

Collidinic acid can be used in the spectrophotometric determination of iron.[4]
