Chemical Structure

2-Ethynyl-1-methylpiperidine CAS 51498-56-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 123.20 g/mol gives 2-Ethynyl-1-methylpiperidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Ethynyl-1-methylpiperidine (CAS 51498-56-7) is a high-purity analytical reference standard with the molecular formula C8H13N and a molecular weight of 123.20 g/mol.

The molecular framework of 2-Ethynyl-1-methylpiperidine (C8H13N) 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
