Neopentyl Glycol

Neopentyl glycol, also known as Dimethylolpropan, is a colorless-to-white, hygroscopic crystalline, organic chemical compound that is used in the synthesis of paints, polyesters, lubricants, and plasticizers.  The combustible, slightly toxic compound can be harmful if ingested or is absorbed through skin contact. It is known to cause skin and eye irritation.


The chemical formula for Neopentyl glycol is C5H12O2. Its CAS is 126-30-7. The crystalline substance is synthesized industrially by the aldol reaction of formaldehyde and isobutyraldehyde, which creates the intermediate hydroxypivaldehyde. This can be converted to Neopentyl glycol with either excess formaldehyde or catalytic hydrogenation of the aldehyde group to an alcohol group.

Neopentyl glycol is soluble in water, benzene, chloroform, and very soluble in ethanol and diethyl ether.

The industrial uses for the combustible organic compound include dyes, functional fluids in closed systems, intermediates, lubricants and lubricant additives, paint and coating additives, and processing aids specific to petroleum production.

Consumer uses include adhesives and sealants, paints and coatings, and paper products.

Neopentyl glycol is available for shipping throughout the continental United States with one (1) week lead time. Neopentyl glycol is a colorless-to-white hygroscopic crystalline powder packed in 55lb and 2200lb bags. Special packaging is available on request, packaging and lead time subject to change.
