Malodorous sulfur compound

Malodorous sulfur compounds are a group of organic and inorganic sulfur-containing chemicals characterized by their extremely strong, pungent, and often unpleasant odors. The best-known members include hydrogen sulfide (H₂S), methanethiol, and various thiols and mercaptans. Formed naturally through the decomposition of organic matter under anaerobic conditions, they are also produced in industrial processes (e.g., pulp and paper, oil refining) and present as key contributors to odors in wastewater, sewage, spoiled food, certain vegetables (onion, garlic), and environmental pollution[1][2][3]. Beyond olfactory impact, these compounds can be acutely toxic (notably hydrogen sulfide), corrosive to metals and infrastructure, and serve as flavor or aroma contributors at trace levels in foods and beverages[1][3][4]. As a group, they do not act as therapeutic targets, receptors, or well-defined enzymes, and "Malodorous sulfur compounds" is not a canonical drug target entity.
