Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 435.30 g/mol gives Baclofen Impurity 69 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Baclofen Impurity 69 (CAS CATO-C4X-101269), a pharmacopoeial impurity reference standard (molecular formula C21H20Cl2N2O4, MW 435.30 g/mol) used for the identification and quantification of trace impurities in APIs.
Baclofen Impurity 69 (C21H20Cl2N2O4) 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).
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 Baclofen Impurity 69 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.
