Definition
US FDA substance register · UNII 7XOO2LE6G3 · registered name 1,4-Butanediol · single chemical substance
Butane-1,4-diol is a butanediol that is butane in which one hydrogen of each of the methyl groups is substituted by a hydroxy group. A colourless, water-miscible, viscous liquid at room temperature (m.p. 16C) with a high boiling point (230C), it is mainly used for the production of other organic chemicals, particularly the solvent oxolane (also known as tetrahydrofuran or THF). It has a role as a protic solvent, a prodrug and a neurotoxin. It is a glycol and a butanediol.
