  <class>SmallMolecule</class>
  <description>t-Butyl mercaptan is an organosulfur compound with the formula C4H10S and an average molecular weight of 90.18 g/mol. t-Butyl mercaptan belongs to the alkylthiols, a subclass of thiols within the organic compounds.

This compound serves as an industrial nutrient and flavouring. It is associated with 18 recorded sources, including drinking water and water supply. In the category of household cleaning and consumer products, it is found in soap detergents, perfumes within detergents and soaps, and cigar cigarettes. Within the sector of food, food processing and cookware, it is linked to food preservation, fermentation processes for beer, and the preparation of vinegar, wine, or sparkling wine. Additionally, it is released from electrical and electronic equipment, specifically electrodes, discharge lamps, electric switches, electrically stimulated smoking devices, conductors or conductive bodies characterised by the conductive materials, and five other sources. The recorded exposure route for t-Butyl mercaptan is oral.</description>
