Glutaric Acid Formula

The glutaric acid formula, also known as Pentanedioic acid formula or n-Pyrotartaric acid formula is discussed in this article. It is an alpha,omega-dicarboxylic acid which has simple 5 carbon linear dicarboxylic acid (HO2C−R−CO2H). The molecular or chemical formula of Glutaric acid is C5H8O4.

When pentanedioic acid is present in a high amount it acts as a metabotoxin and as an acidogen. It can be synthesized by the following process

  1. The ring-opening of butyrolactone (C4H6O2) with potassium cyanide (KCN) to produce potassium carboxylate-nitrile. It is hydrolyzed further to diacid. Oxidizing dihydropyran will produce glutaric acid.
  2. It can also be synthesized by treating 1,3-dibromopropane with potassium or sodium cyanide to produce dinitrile. Further, it is hydrolysed to obtain glutaric acid.

Properties Of Glutaric acid Formula

Chemical formula  C5H8O4
Molecular weight  132.12 g/mol
Melting point  95 to 98 °C
Boiling point  200 °C

n-Pyrotartaric acid is naturally produced by the body during the process of metabolism of certain amino acids, which include tryptophan and including lysine. Any defect in the pathway can cause disorder such as glutaric aciduria which results in severe encephalopathy.

Use Of Glutaric Acid

  • Hydrogenation of glutaric acid and its derivatives produces a placticizers.
  • Used to produce many polymers such as polyesters, polyamides.
