Used as an intermediate in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) where the piperazine ring serves as a key structural motif. The tert-butyl carbamate (Boc) group provides protection for the amine during multi-step reactions, allowing selective reactivity at other sites. After the desired transformations, the Boc group can be easily removed under mild acidic conditions to liberate the free amine. This compound is valuable in medicinal chemistry for constructing drug candidates targeting central nervous system disorders, metabolic diseases, and oncology, due to the favorable pharmacokinetic properties imparted by the methylpiperazine moiety.
