Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Cetirizine Impurity 62 DiHCl (Mixture of Isomers).
CATO supplies Cetirizine Impurity 62 DiHCl (Mixture of Isomers) (CAS CATO-C4X-108362), a pharmacopoeial impurity reference standard (molecular formula C24H31ClN2O4HCl, MW 483.43 g/mol) used for the identification and quantification of trace impurities in APIs.
Cetirizine Impurity 62 DiHCl (Mixture of Isomers) (C24H31ClN2O4HCl) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Cetirizine Impurity 62 DiHCl (Mixture of Isomers) 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.
