Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 242.27 g/mol gives Carbamazepine Impurity 31 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Carbamazepine Impurity 31 (CAS CATO-C4X-118131) is a certified pharmaceutical impurity reference standard with the molecular formula C14H14N2O2 and a molecular weight of 242.27 g/mol.
Carbamazepine Impurity 31 (C14H14N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Carbamazepine Impurity 31 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.
