2-[(E)-2-({1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-pyrrol-2-yl}methylidene)hydrazin-1-yl]-3-(trifluoromethyl)quinoxaline (CAS 477873-15-7), molecular formula C20H11ClF6N6 and molecular weight 484.78 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 2-[(E)-2-({1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-pyrrol-2-yl}methylidene)hydrazin-1-yl]-3-(trifluoromethyl)quinoxaline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 484.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-[(E)-2-({1-[3-chloro-5-(trifluoromethyl)pyridin-2-yl]-1H-pyrrol-2-yl}methylidene)hydrazin-1-yl]-3-(trifluoromethyl)quinoxaline 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.
