Description
CATO manufactures Alprazolam EP Impurity I(Enantiomer Mixture) 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.
CATO supplies Alprazolam EP Impurity I(Enantiomer Mixture) (CAS CATO-C4X-146017), a pharmacopoeial impurity reference standard (molecular formula C34H27Cl2N7O2, MW 636.54 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Alprazolam EP Impurity I(Enantiomer Mixture) (C34H27Cl2N7O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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.
