Description
CATO manufactures chondroitin sulfate 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.
chondroitin sulfate impurity E (CAS CATO-C4X-32815) is a certified pharmaceutical impurity reference standard with the molecular formula C14H20NO17S2Na and a molecular weight of 561.41 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, an ether linkage, chondroitin sulfate impurity E is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 561.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
