Hydrochlorothiazide Impurity 9 CAS 364-96-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Hydrochlorothiazide Impurity 9.

CATO supplies Hydrochlorothiazide Impurity 9 (CAS 364-96-5), a pharmacopoeial impurity reference standard (molecular formula C8H6Cl2N2O2S, MW 265.12 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Hydrochlorothiazide Impurity 9 (C8H6Cl2N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Hydrochlorothiazide Impurity 9 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.
