Description
CATO supplies 2-(4-((E)-2-(5-((E)-2-(Benzyloxy)-4-(dibutylamino)styryl)thiophen-2-yl)vinyl)-3-cyano-5-phenyl-5-(trifluoromethyl)furan-2(5H)-ylidene)malononitrile (CAS 1267603-73-5), a certified reference material (molecular formula C44H39F3N4O2S, MW 744.87 g/mol) for analytical method development and quality control.
The molecular framework of 2-(4-((E)-2-(5-((E)-2-(Benzyloxy)-4-(dibutylamino)styryl)thiophen-2-yl)vinyl)-3-cyano-5-phenyl-5-(trifluoromethyl)furan-2(5H)-ylidene)malononitrile (C44H39F3N4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(4-((E)-2-(5-((E)-2-(Benzyloxy)-4-(dibutylamino)styryl)thiophen-2-yl)vinyl)-3-cyano-5-phenyl-5-(trifluoromethyl)furan-2(5H)-ylidene)malononitrile 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.
