Organosulfur compounds are organic compounds that contain a carbon-sulfur bond. They are a diverse group of molecules found in both natural and synthetic forms. Sulfur atoms can be incorporated into organic molecules in various ways, leading to different functional groups and properties.

Common organosulfur functional groups include thiols (or mercaptans), which have a sulfhydryl group (-SH) bonded to a carbon atom, and sulfides (or thioethers), which have a sulfur atom bonded to two carbon atoms. Disulfides, with a sulfur-sulfur single bond (-S-S-), are also significant, playing crucial roles in protein structure. Thioesters and sulfonates are other important classes.

Many organosulfur compounds are known for their distinctive odors. For example, thiols are responsible for the smell of garlic, onions, and skunk spray. The aroma of coffee and roasted meats also involves organosulfur compounds.

In biological systems, organosulfur compounds are essential. The amino acids methionine and cysteine are vital building blocks for proteins, and the disulfide bonds between cysteine residues stabilize protein structures. Coenzymes like biotin and thiamine also contain sulfur.

Industrially, organosulfur compounds have numerous applications. They are used as pharmaceuticals, pesticides, vulcanizing agents for rubber, and as components in fuels and lubricants. The synthesis and study of organosulfur chemistry are active areas of research due to their widespread importance.
