4-Phenylpiperidine-4-carboxylic acid

4-Phenylpiperidine-4-carboxylic acid (CAS 83949-32-0 ) is a piperidine-based building block used in pharmaceutical synthesis. It provides a quaternary carbon center with both an amine and a carboxylic acid handle.

This makes it a structurally valuable intermediate for constructing complex drug candidates. The compound is primarily sourced as an intermediate in the synthesis of CNS-active pharmaceutical compounds.

Its rigid piperidine-phenyl scaffold contributes to target selectivity in various applications. Medicinal chemistry programs use it to build libraries of analgesic, antipsychotic, or receptor-modulating candidates.

During lead optimization, it serves as a critical component for molecular design. In biotechnology and life sciences research, it supports the preparation of reference standards and labeled compounds.

These materials are essential for pharmacological assays and metabolic studies. Contract manufacturers and API producers incorporate it at the gram-to-kilogram scale during drug development workflows.

The product is supplied as a white to off-white crystalline powder. It is available in research quantities through fine chemical suppliers, with larger quantities available for process chemistry.

Material is typically offered to pharmaceutical-grade purity specifications. Each batch includes certificate of analysis documentation supporting GMP-adjacent procurement requirements for industrial use.
