Chemical Structure

α-Ethynyl-3-pyridinemethanol CAS 276884-35-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including α-Ethynyl-3-pyridinemethanol.

α-Ethynyl-3-pyridinemethanol (CAS 276884-35-6) is a high-purity analytical reference standard with the molecular formula C8H7NO and a molecular weight of 133.15 g/mol.

The molecular framework of α-Ethynyl-3-pyridinemethanol (C8H7NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.

As a certified reference material (CRM), α-Ethynyl-3-pyridinemethanol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
