Product Application of 1,4-Butanediol CAS# 110-63-4
Butanediol and its derivatives are widely used across the chemical industry, including technical plastics, polyurethanes, solvents, electronic chemicals and elastic fibres. 1,4-Butanediol is used in synthesizing epothilones, a new category of anticancer medicines. It is also applied in the stereoselective synthesis of (-)-Brevisamide. The largest application of 1,4-Butanediol is in tetrahydrofuran (THF) production, which is used to manufacture polytetramethylene ether glycol, mainly for spandex fibers, urethane elastomers, and copolyester ethers.
