Glutaric acid, Pentanedioic acid, 99%

Glutaric acid is the organic compound with the formula C3H6(COOH)2 . Although the related "linear" dicarboxylic acids adipic and succinic acids are water-soluble only to a few percent at room temperature, the water-solubility of glutaric acid is over 50% (w/w).

Glutaric acid itself has been used in the production of polymers such as polyester polyols, polyamides. The odd number of carbon atoms (i.e. 5) is useful in decreasing polymer elasticity. 1.5-Pentanediol, a common plasticizer and precursor to polyesters is manufactured by hydrogenation of glutaric acid and its derivatives.
