CATO supplies (2E)-1-[4-(1H-1,3-Benzodiazol-1-yl)phenyl]-3-[(4-methylphenyl)amino]prop-2-en-1-one (CAS 691887-93-1), a certified reference material (molecular formula C23H19N3O, MW 353.42 g/mol) for analytical method development and quality control.
The molecular framework of (2E)-1-[4-(1H-1,3-Benzodiazol-1-yl)phenyl]-3-[(4-methylphenyl)amino]prop-2-en-1-one (C23H19N3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
As a certified reference material (CRM), (2E)-1-[4-(1H-1,3-Benzodiazol-1-yl)phenyl]-3-[(4-methylphenyl)amino]prop-2-en-1-one 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.
