1,4-Butanediol, also called Butane-1,4-diol (other names include 1,4-B, BD, BDO, and 1,4-BD), is a primary alcohol and an organic compound with the formula HOCH₂CH₂CH₂CH₂OH. It is a colorless viscous liquid first synthesized in 1890 via acidic hydrolysis of N,N'-dinitro-1,4-butanediamine by Dutch chemist Pieter Johannes Dekkers, who called it "tetramethylene glycol".
