Used as a protected intermediate in organic synthesis, particularly in pharmaceutical manufacturing. The 2-(trimethylsilyl)ethoxycarbonyl (Teoc) group acts as a protecting group for the piperidine nitrogen, allowing selective reactions at other functional sites. The 4-oxopiperidine moiety is common in bioactive molecules, making this compound valuable in the development of medicinal compounds, especially central nervous system agents and kinase inhibitors. It enables efficient construction of complex molecules through controlled deprotection and coupling steps under mild conditions.
