Chemical Structure

Xylometazoline EP Impurity A CAS 94266-17-8 chemical structure

Description

CATO supplies Xylometazoline EP Impurity A (CAS 94266-17-8), a pharmacopoeial impurity reference standard (molecular formula C16H26N2O, MW 262.39 g/mol) used for the identification and quantification of trace impurities in APIs.

Xylometazoline EP Impurity A (C16H26N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), Xylometazoline EP Impurity A meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
