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 (2Z)-N-[4-(1H-1,3-Benzodiazol-2-yl)phenyl]-2-[(3,4-dimethylphenyl)imino]-2H-chromene-3-carboxamide.
(2Z)-N-[4-(1H-1,3-Benzodiazol-2-yl)phenyl]-2-[(3,4-dimethylphenyl)imino]-2H-chromene-3-carboxamide (CAS 478342-84-6), molecular formula C31H24N4O2 and molecular weight 484.55 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2Z)-N-[4-(1H-1,3-Benzodiazol-2-yl)phenyl]-2-[(3,4-dimethylphenyl)imino]-2H-chromene-3-carboxamide (C31H24N4O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).
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.
CATO manufactures (2Z)-N-[4-(1H-1,3-Benzodiazol-2-yl)phenyl]-2-[(3,4-dimethylphenyl)imino]-2H-chromene-3-carboxamide 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.
