Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in organic reactions where the oxime group can be modified or reduced to form amine derivatives. Its benzyl-protected aldehyde functionality allows selective deprotection and further functionalization in multi-step syntheses. Commonly employed in medicinal chemistry for structure-activity relationship studies due to its ability to mimic bioactive scaffolds.
