Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 264.24 g/mol gives Sulfadiazine lmpurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sulfadiazine lmpurity 4 (CAS CATO-C4X-150414) is a certified pharmaceutical impurity reference standard with the molecular formula C10H12N6O3 and a molecular weight of 264.24 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Sulfadiazine lmpurity 4 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Sulfadiazine lmpurity 4 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.
