Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Viloxazine Impurity 3.
CATO supplies Viloxazine Impurity 3 (CAS CATO-C4X-31313), a pharmacopoeial impurity reference standard (molecular formula C9H10O3, MW 166.17 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Viloxazine Impurity 3 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.17 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.
CATO manufactures Viloxazine Impurity 3 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.
