Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where primary amine functionality is required for coupling reactions such as amide or urea formation. The hydrochloride salt form enhances stability and solubility, facilitating its use in multi-step organic syntheses. Commonly employed in the preparation of agrochemicals and fine chemicals due to its favorable reactivity profile. Also utilized in the creation of specialty polymers and ligands for catalysis, where the benzylamine structure with meta-tert-butyl substituent contributes to electronic and steric properties.
