Used as a key intermediate in the synthesis of certain pharmaceuticals, particularly in the production of selective adrenergic receptor agonists and antagonists. It serves in the development of drugs targeting cardiovascular and respiratory conditions due to its structural compatibility with bioactive molecules. Its chlorinated aromatic core and amine functionality allow for further chemical modifications, making it valuable in medicinal chemistry for optimizing drug potency and selectivity. Also employed in research settings for designing novel compounds with potential therapeutic effects.
