Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of active pharmaceutical ingredients (APIs) where piperazine rings are structural components. Its tert-butoxycarbonyl (Boc) protection allows for selective reactivity, making it valuable in multi-step organic syntheses. The methoxymethyl group enhances solubility and can act as a protecting group for alcohols or as a linker in prodrug strategies. Commonly employed in medicinal chemistry for drug discovery programs targeting central nervous system disorders, metabolic diseases, and infectious diseases due to the versatility of the piperazine scaffold.
