Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) disorders. Its structure allows for the introduction of benzyl and amino groups, making it valuable in constructing complex molecules for drug discovery. Commonly employed in the preparation of kinase inhibitors and receptor modulators due to its favorable reactivity and stereochemistry. Also utilized in medicinal chemistry for optimizing pharmacokinetic properties such as solubility and metabolic stability.
