Molecular Structure of Neopentyl glycol (CAS NO.126-30-7):
Neopentyl glycol (CAS NO.126-30-7) is used in the sythesis of polyesters, paints, lubricants, and plasticizers. When used in the manufacture of polyesters, it enhances the product's stability toward heat, light, and water.
Neopentyl glycol is synthesized industrially by the aldol reaction of formaldehyde and isobutyraldehyde.

NSC 55836 ; Neol ; Neopentanediol ; Neopentylene glycol . Neopentyl glycol (CAS NO.126-30-7) is white crystalline solid. It is stable and incompatible with strong oxidizing agents, acetic anhydride, acid chlorides, moisture. It is combustible.
It can emit toxic fumes under fire condition. Neopentyl glycol may generate toxic gases in combination of with alkali metals, nitrides, and strong reducing agents. Reacts with inorganic acids and carboxylic acids to form esters plus water. Converted to aldehydes or acids by oxidizing agents. May initiate the polymerization of isocyanates and epoxides. It may be harmful by ingestion or skin absorption. Causes eye and skin irritation. Material is irritating to mucous membrane and upper respiratory tract.
