Olsalazine EP Impurity E CAS CATO-C4X-18015

Description

Compared with other compounds in its class, the molecular weight of 380.33 g/mol gives Olsalazine EP Impurity E distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Olsalazine EP Impurity E (CAS CATO-C4X-18015), a pharmacopoeial impurity reference standard (molecular formula C15H12N2O8S, MW 380.33 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Olsalazine EP Impurity E is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 380.33 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 Olsalazine EP Impurity E 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.
