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 (E)-2-(trifluoromethyl)-3-(2-(4-(trifluoromethyl)benzylidene)hydrazinyl)quinoxaline.
(E)-2-(trifluoromethyl)-3-(2-(4-(trifluoromethyl)benzylidene)hydrazinyl)quinoxaline (CAS 338962-25-7), molecular formula C17H10F6N4 and molecular weight 384.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, (E)-2-(trifluoromethyl)-3-(2-(4-(trifluoromethyl)benzylidene)hydrazinyl)quinoxaline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.28 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (E)-2-(trifluoromethyl)-3-(2-(4-(trifluoromethyl)benzylidene)hydrazinyl)quinoxaline 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.
