Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of biologically active molecules that require cyclobutane-based scaffolds. Its aldehyde functionality allows for further derivatization through reactions such as reductive amination or Wittig transformations, enabling the construction of complex amine-containing structures. The tert-butyl carbamate (Boc) group provides amine protection during multi-step syntheses, ensuring selective reactivity and stability under various reaction conditions. Commonly employed in medicinal chemistry for optimizing drug candidates targeting CNS disorders and metabolic diseases.
