Used primarily as an intermediate in the synthesis of pharmaceuticals and fine chemicals. It plays a role in the production of certain central nervous system agents and decongestants due to its structural similarity to amphetamines. Commonly employed in research settings for developing compounds with stimulant or psychoactive properties. Also utilized in the preparation of chiral catalysts and resolving agents in asymmetric synthesis. Its hydrochloride salt form enhances stability and handling in industrial processes.
