Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and muscle relaxants. Its structure supports the creation of bioactive molecules due to the presence of both amine and carbonyl functional groups, enabling diverse chemical modifications. Commonly employed in medicinal chemistry for building isoquinoline-based compounds with potential therapeutic effects, including analgesic and anti-inflammatory properties. Also utilized in research settings for designing novel heterocyclic compounds for drug discovery.
