Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of selective adrenergic receptor agonists and antagonists. It serves in the preparation of active pharmaceutical ingredients (APIs) for cardiovascular and central nervous system drugs. Its chiral structure makes it valuable in asymmetric synthesis, where stereochemistry plays a critical role in drug efficacy. Also employed in agrochemical research for developing herbicides and plant growth regulators due to the presence of dichlorophenyl moiety, which can enhance bioactivity. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving phenylalkylamine derivatives.
