What is 2,2-Dimethyl-1,3-propanediol/ neopentyl glycol？

neopentyl glycol is a highly versatile and valuable polyhydric alcohol characterized by its unique molecular structure featuring two primary hydroxyl groups and a quaternary carbon atom. This structure imparts exceptional chemical stability, weather resistance, and thermal stability to its derivatives. NPG is widely recognized for its crucial role in producing high-performance polyester resins, polyurethanes, and synthetic lubricants. Its symmetrical neopentyl structure provides excellent hydrolysis resistance, UV stability, and color retention, making it an essential raw material for premium coating systems and specialty chemical applications.
