Used in pharmaceutical research as an intermediate in the synthesis of biologically active compounds, particularly kinase inhibitors. Its structure supports binding to specific enzyme targets involved in signal transduction pathways, making it valuable in the development of treatments for cancer and inflammatory diseases. The cyano and morpholinopiperidine groups enhance solubility and target affinity, while the tert-butyl ester protects the carboxylic acid during synthesis, allowing selective deprotection later in the drug manufacturing process.
