Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of sulfur-containing bioactive compounds. Its structure allows for the introduction of the 4-tert-butylthiophenyl group, which can enhance lipophilicity and metabolic stability in drug design. Commonly employed in the preparation of fungicides and herbicides due to the favorable electronic and steric properties of the tert-butyl and thioamide functionalities. Also serves as a building block in organic synthesis for constructing heterocyclic systems through cyclization reactions.
