Description
CATO manufactures Pantoprazole Impurity 56 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.
Pantoprazole Impurity 56 (CAS 172282-50-7 (free bass)) is a certified pharmaceutical impurity reference standard with the molecular formula C7H8F2N2OHCl and a molecular weight of 210.61 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Pantoprazole Impurity 56 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.61 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.
