What is "neopentyl glycol"

n. (context organic chemistry English) The diol ''2,2-dimethyl-1,3-propanediol'' derived from neopentane

Neopentyl glycol ( IUPAC name 2,2-dimethyl-1,3-propanediol) is an organic chemical compound. It is used in the synthesis of polyesters, paints, lubricants, and plasticizers. When used in the manufacture of polyesters, it enhances the stability of the product towards heat, light, and water. By esterification reaction with fatty or carboxylic acids, synthetic lubricating esters with reduced potential for oxidation or hydrolysis, compared to natural esters, can be produced.
