Chemical Properties
white to light beige crystalline powder
Uses
Citraconic acid is used in synthetic or copolymer oils, in treating metals for adhesion of polyolefins, and in thermoplastics.
Uses
Citraconic acid is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuff fields.
Definition
ChEBI: Citraconic acid is a dicarboxylic acid consisting of maleic acid having a methyl substituent at the 2-position. It has a role as a human metabolite. It is a dicarboxylic acid and a dicarboxylic fatty acid. It is functionally related to a maleic acid. It is a conjugate acid of a citraconate(2-).
Purification Methods
Steam distil and crystallise it from EtOH/ligroin. [Beilstein 2 H 768, 2 I 309, 2 II 652, 2 III 1938, 2 IV 2230.]
