Description
CATO manufactures Tranexamic Acid 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.
CATO supplies Tranexamic Acid EP Impurity E (CAS 82755-59-7), a pharmacopoeial impurity reference standard (molecular formula C16H28N2O3, MW 296.41 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Tranexamic Acid EP Impurity E is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.41 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.
