(E)-4-((4-nitrobenzylidene)amino)phenyl 4-(tert-butyl)benzoate CAS 331460-54-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4-((4-nitrobenzylidene)amino)phenyl 4-(tert-butyl)benzoate.

(E)-4-((4-nitrobenzylidene)amino)phenyl 4-(tert-butyl)benzoate (CAS 331460-54-9), molecular formula C24H22N2O4 and molecular weight 402.44 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-4-((4-nitrobenzylidene)amino)phenyl 4-(tert-butyl)benzoate (C24H22N2O4) is characterized by a flavonoid core, 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 (E)-4-((4-nitrobenzylidene)amino)phenyl 4-(tert-butyl)benzoate 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.
