Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tegoprazan impurity 23.
CATO supplies Tegoprazan impurity 23 (CAS CATO-C4X-229723), a pharmacopoeial impurity reference standard (molecular formula C20H20FN3O3, MW 369.39 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Tegoprazan impurity 23 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 369.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Tegoprazan impurity 23 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.
