Description
CATO manufactures Formoterol Impurity 86 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 Formoterol Impurity 86 (CAS CATO-C4X-152586), a pharmacopoeial impurity reference standard (molecular formula C15H11Br2NO4, MW 429.06 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Formoterol Impurity 86 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 429.06 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.
