Pimelic acid CAS:111-16-0 is the organic compound with the formula HO2C(CH2)5CO2H. Pimelic acid is one CH2 unit longer than a related dicarboxylic acid, adipic acid, a precursor to many polyesters and polyamides. However compared to adipic acid, pimelic acid is relatively small importance industrially.[2] Derivatives of pimelic acid are involved in the biosynthesis of the amino acid lysine and the vitamin biotin.
