Reported present in beer | [Uses]
3-Methyl-1-butanethiol, is a versatile organic building block in the synthesis of sulfur containnig pharmaceutical compounds. It is used in the synthesis of some poly(alkylene glycol dithiophosphates) with functional groups in the S-alkyl radical, possessing long-lasting anthelminthic and antibacterial properties. It is also shown to be one of the flavor components from beef, pork, and chicken | [Definition]
