butylene glycol
Also known as 1,3-butylene glycol, beta-Butylene glycol, Methyltrimethylene glycol, Butane-1,3-diol, 1-Methyl-1,3-propanediol, 1,3-Dihydroxybutane, 1,3 Butylene glycol, (RS)-1,3-Butandiol
1,3-Butanediol is an organic compound with the formula CH3CH(OH)CH2CH2OH, not to be confused with 1,4 Butanediol. With two alcohol functional groups, the molecule is classified as a diol. The compound without the R (or D) designation is racemic, which is what has been used in most studies before 2023. The compound is a colorless, bittersweet, water-soluble liquid. It is one of four common structural isomers of butanediol. It is used in grape flavoring, and as a precursor to some antibiotics.

==Production and uses== Hydrogenation of 3-hydroxybutanal gives 1,3-butanediol: CH3CH(OH)CH2CHO + H2 → CH3CH(OH)CH2CH2OH Dehydration of 1,3-butanediol gives 1,3-butadiene: CH3CH(OH)CH2CH2OH → CH2=CH-CH=CH2 + 2H2O
