(S)-2-Ethynylpiperidine CAS 128959-95-5

Description

The occurrence of (S)-2-Ethynylpiperidine is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-2-Ethynylpiperidine (CAS 128959-95-5) is a high-purity analytical reference standard with the molecular formula C7H11N and a molecular weight of 109.17 g/mol.

The molecular framework of (S)-2-Ethynylpiperidine (C7H11N) is characterized by a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures (S)-2-Ethynylpiperidine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
