Butanethiol is a volatile, clear to yellowish liquid with a fetid odor and it is chemically classified among the thiols. Butanethiol is prepared by the free radical catalyzed addition of hydrogen sulfide to 1-butene. Butanethiol is a thiol of low molecular weight, and it is highly flammable. Butanethiol is used as an industrial solvent,and as an intermediate for cotton defoliants. It is sometimes placed in the "stink bombs" and "stink perfumes" for pranksters.1-Butanethiol is a flavouring agent. 1-Butanethiol is present in beef, Cheshire cheese, raw chicken and cooked potatoes 1-butanethiol belongs to the family of Alkylthiols.
