Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) that require functionalized piperidine scaffolds. Its aldehyde group allows for further chemical transformations such as reductive amination or condensation reactions, enabling the construction of complex nitrogen-containing heterocycles. Commonly employed in medicinal chemistry for drug discovery programs targeting central nervous system disorders, metabolic diseases, and oncology. Also utilized in the preparation of chiral building blocks for asymmetric synthesis.
