Dimethyl Sulfide (DMS) is a colorless, volatile liquid with a strong, distinctive odor often described as similar to that of cabbage or seafood. It is a naturally occurring compound produced by marine phytoplankton and is also found in some plants and animals. DMS plays a significant role in the Earth's sulfur cycle and is involved in cloud formation and climate regulation. In addition to its natural sources, DMS is used in various industrial applications, including as a solvent and in the production of other chemicals. It can also be found in some food products, contributing to flavor profiles. Its chemical formula is C2H6S.
