Applications & Uses
Description
Pimelic acid is the organic compound with the formula HO2C(CH2)5CO2H which has been synthesized from cyclohexanone and from salicylic acid. In the former route, the additional carbon is supplied by dimethyloxalate, which reacts with the enolate.This acid (heptanedioic acid), from the Greek pimelh (pimele fat), as adipic acid, was isolated from oxidized fats. It was obtained in 1884 by Ganttner F et al. as a product of ricinoleic acid (hydroxylated oleic acid) from castor oil.
Uses
The major uses of pimelic acid are in plasticizers and polymers.
Uses
Pimelic Acid is a metabolite found in four biofluids from dairy cows that may be used as biomarkers of milk.
