Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 242.66 g/mol gives Baclofen impurity 7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Baclofen impurity 7 (CAS 103857-58-5), a pharmacopoeial impurity reference standard (molecular formula C11H11ClO4, MW 242.66 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C11H11ClO4, Baclofen impurity 7 contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 242.66 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 7 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.
