Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
2-{2-[(E)-2-phenylethenyl]-1H-1,3-benzodiazol-1-yl}-N-[4-(trifluoromethoxy)phenyl]acetamide (CAS 400081-21-2) is a high-purity analytical reference standard with the molecular formula C24H18F3N3O2 and a molecular weight of 437.41 g/mol.
2-{2-[(E)-2-phenylethenyl]-1H-1,3-benzodiazol-1-yl}-N-[4-(trifluoromethoxy)phenyl]acetamide (C24H18F3N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 2-{2-[(E)-2-phenylethenyl]-1H-1,3-benzodiazol-1-yl}-N-[4-(trifluoromethoxy)phenyl]acetamide 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.
