Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 606.66 g/mol gives Aceclofenac Impurity 21 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Aceclofenac Impurity 21 (CAS CATO-C4X-153121) is a certified pharmaceutical impurity reference standard with the molecular formula C34H49Cl2NO4 and a molecular weight of 606.66 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Aceclofenac Impurity 21 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 606.66 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 Aceclofenac Impurity 21 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.
