Dimethyl sulfide (DMS) is a naturally occurring organosulfur compound with a strong, pungent odor, widely used in flavor and fragrance industries, as well as in marine biology research for its role in atmospheric sulfur cycles. It is also employed as a precursor in organic synthesis and as a solvent in specialized applications. Industrially, it serves as an odorant for fuel gas, a sulfiding agent for refinery catalysts, and an intermediate in dimethyl sulfoxide manufacture. This chemical has a CAS number of 75-18-3, a molecular formula of (CH3)2S, and a molecular weight of 62.13 g/mol. It is typically stored at ambient temperatures but requires careful handling due to its hazardous nature, indicated by its "Danger" signal word. Molekula supplies dimethyl sulfide from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
