Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting central nervous system disorders. Its structure allows for selective modifications, making it valuable in developing anxiolytic and anticonvulsant agents. It is also employed in the preparation of kinase inhibitors and other heterocyclic systems in medicinal chemistry research. Due to its reactive chloromethyl group, it readily undergoes alkylation and substitution reactions, facilitating conjugation in drug design and development.
