Pharmaceutical intermediate
Used as an intermediate in the synthesis of active pharmaceutical ingredients and candidate molecules. The free piperidine NH offers a convenient handle for acylation, alkylation, reductive amination and coupling chemistry.
Heterocyclic building block
Serves as a piperidine- and pyrrolidinone-containing scaffold in medicinal chemistry library design. The combined ring system is a common motif when exploring structure-activity relationships.
Discovery and process chemistry
Applied in research-scale route scouting and small-scale process development as a defined C11 fragment. Its dual nitrogen functionality supports rapid diversification toward more complex targets.
Reference and laboratory reagent
Employed as a laboratory reagent and structural reference material in method development and analytical work. Suitable for general synthetic and research applications where a characterised lactam-piperidine fragment is required.
