butane12diol
Butane-1,2-diol, commonly written as 1,2-butanediol, is a four-carbon difunctional alcohol with the chemical formula C4H10O2. It contains two hydroxyl groups on adjacent carbon atoms, making it a diol and a versatile building block in organic synthesis. The molecule has one stereogenic center at carbon-2, giving two enantiomers (R and S); commercial samples are often sold as a racemate.
Physically, butane-1,2-diol is a colorless, viscous liquid that is miscible with water and many organic solvents.
Production and sources vary. Industrial routes include chemical synthesis from carbonyl-containing precursors via hydrogenation and related
Uses and applications are broad. It serves as a solvent in coatings, dyes, and electronics, and as
Safety and handling: butane-1,2-diol is flammable and can irritate skin, eyes, and the respiratory tract. It should
