Metabolite Identification
Common Name1-Butanethiol
Description1-Butanethiol, also known as 1-butyl mercaptan or 1-butylthiol, belongs to the class of organic compounds known as alkylthiols. These are organic compounds containing the thiol functional group linked to an alkyl chain. 1-Butanethiol is a coffee, egg, and garlic tasting compound. 1-Butanethiol has been detected, but not quantified, in milk and milk products and potato. Commercially, this is performed using ultraviolet light. It is sometimes placed in the "stink bombs" and "stink perfumes" for pranksters. Butanethiol is a very noxious and caustic chemical compound, and at sufficiently high concentrations, it produces serious health effects in both humans and animals, especially as a result of prolonged exposure. It may cause effects on the thyroid and the nervous system and could cause lowering of consciousness. The scent of butanethiol is so strong that the human nose can easily detect it in the air at concentrations as low as 10 parts per billion. The substance irritates the eyes, the skin, and the respiratory tract. 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. The threshold level for 1-butanethiol is reported as 1.4 ppb. Butanethiol is chemically classified among the thiols, which are organic compounds with molecular formulas and structural formulas similar to alcohols, except that sulfur-containing sulfhydryl group (-SH) replaces the oxygen-containing hydroxyl group (-OH) in the molecule. Butanethiol is prepared by the free radical catalyzed addition of hydrogen sulfide to 1-butene. Contact with the skin and mucous membranes causes burns, and contact with the eyes can lead to blurred vision or complete blindness. Inhalation may cause weakness, confusion, cough, dizziness, drowsiness, headache, nausea, vomiting, and shortness of breath.
