3-Methyl-2-butene-1-thiol

Description:
3-Methyl-2-butene-1-thiol, with the CAS number 5287-45-6, is an organic compound classified as a thiol, which contains a sulfur atom bonded to a carbon atom and a hydrogen atom. This compound features a branched alkene structure, characterized by a double bond between the second and third carbon atoms in the butene chain, along with a thiol functional group (-SH) at the terminal position. It is typically a colorless liquid with a strong, pungent odor, reminiscent of garlic or onion, which is common among thiols. The presence of the double bond contributes to its reactivity, making it susceptible to addition reactions. 3-Methyl-2-butene-1-thiol is soluble in organic solvents but has limited solubility in water due to its hydrophobic hydrocarbon chain. It is used in various applications, including as a flavoring agent and in organic synthesis. Safety precautions should be taken when handling this compound, as thiols can be toxic and irritating to the skin and respiratory system.
