Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) involving piperazine derivatives. Its structure allows for selective modifications, making it valuable in creating compounds with biological activity, such as antimicrobial, antiviral, and central nervous system agents. Commonly employed in medicinal chemistry for building complex heterocyclic systems where controlled functionalization is required. Also utilized in research settings for designing novel drug candidates due to its stability and reactivity profile.
