Chemical Structure

6-Chloro-4-hydroxy-5-methylpyridin-2(1H)-one hydrochloride CAS 95306-65-3 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 6-Chloro-4-hydroxy-5-methylpyridin-2(1H)-one hydrochloride.

6-Chloro-4-hydroxy-5-methylpyridin-2(1H)-one hydrochloride (CAS 95306-65-3), molecular formula C6H6ClNO2HCl and molecular weight 196.03 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 6-Chloro-4-hydroxy-5-methylpyridin-2(1H)-one hydrochloride (C6H6ClNO2HCl) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 196.03 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 6-Chloro-4-hydroxy-5-methylpyridin-2(1H)-one hydrochloride 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.
