Used in organic synthesis as a chiral building block for pharmaceuticals, particularly in the development of bioactive molecules and asymmetric synthesis. The isothiocyanate group enables conjugation with amines to form thiourea derivatives, which are valuable in medicinal chemistry for designing enzyme inhibitors or receptor ligands. The presence of the methoxyphenyl and chiral center allows for selective interactions in biological systems, making it useful in the preparation of potential neuroprotective or anti-inflammatory agents. Also employed in the synthesis of agrochemicals and functional materials where stereochemistry plays a critical role in activity. Additionally, it serves as a labeling agent for proteins or peptides in biomolecular analysis due to its specific reactivity with primary amine groups (-NH2), enabling clear and detectable modifications.
