Used as a chiral intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals where stereochemistry plays a critical role. Its oxazoline ring and pyrazine moiety make it valuable in developing kinase inhibitors and antimicrobial agents. The (S)-configuration enables selective interactions with biological targets, enhancing efficacy and reducing side effects in drug candidates. Also employed in asymmetric synthesis and catalysis research due to its stable chiral center and heterocyclic framework.
