1-Phenylpiperidine

1-Phenylpiperidine is an aryl-substituted piperidine derivative used as an organic intermediate in selected pharmaceutical intermediate, fine chemical, and specialty synthesis routes. Its structure combines a saturated piperidine ring with a phenyl group attached to the nitrogen atom, providing an N-phenyl piperidine framework for downstream transformation.
