Used primarily as an intermediate in organic synthesis, especially in the development of pharmaceuticals and agrochemicals. Its sulfane (sulfide) functional group allows for further chemical modifications, making it valuable in constructing complex molecules. It serves in the preparation of bioactive compounds where the methylsulfide moiety enhances lipophilicity and metabolic stability. Also utilized in the synthesis of flavor and fragrance compounds due to its aromatic substitution pattern and sulfur-containing group, which can contribute to sensory properties.
