Cas no 623-51-8 (Ethyl 2-mercaptoacetate)
Ethyl 2-mercaptoacetate (CAS 623-51-8) is a sulfur-containing ester with the molecular formula C?H?O?S. This clear to pale yellow liquid is characterized by its strong, unpleasant odor due to the thiol functional group. It serves as a versatile intermediate in organic synthesis, particularly in the production of pharmaceuticals, agrochemicals, and flavor compounds. Its reactive thiol and ester groups enable applications in nucleophilic substitutions, Michael additions, and as a building block for heterocyclic compounds. Ethyl 2-mercaptoacetate is also used in polymer chemistry as a chain transfer agent. Proper handling is essential due to its sensitivity to oxidation and potential irritant properties. Storage under inert atmosphere is recommended to maintain stability.
