Description

Ethyl (Methylthio)Acetate is a versatile sulfur-containing ester, CAS NO 4455-13-4, valued for its role as a key synthetic intermediate and flavor/fragrance component. Its unique structure, featuring both an ester and a thioether functional group, makes it a valuable building block in organic synthesis for introducing sulfur motifs. This compound is primarily sought by manufacturers in the agrochemical, pharmaceutical, and specialty chemical industries for the production of active ingredients and complex molecules.

Application

• Agrochemical Intermediate: A crucial precursor in the synthesis of herbicides, fungicides, and insecticides, where the sulfur moiety enhances biological activity.
• Pharmaceutical Synthesis: Used as a building block for creating sulfur-containing active pharmaceutical ingredients (APIs) and other bioactive compounds.
• Flavor and Fragrance Industry: Imparts savory, meaty, or tropical notes in flavor compositions and is used in fragrance formulations for fruity accords.
• Organic Synthesis Reagent: Serves as an alkylating agent or a source of the (methylthio)acetate group in various organic transformations and material science applications.
• Chemical Research & Development: Employed in academic and industrial R&D labs for exploring new synthetic pathways and novel compound libraries.
