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.
4-(4-Chlorophenyl)-2-[(E)-2-[(4-methoxyphenyl)amino]ethenyl]-6-methylpyridine-3,5-dicarbonitrile (CAS 337924-13-7) is a high-purity analytical reference standard with the molecular formula C23H17ClN4O and a molecular weight of 400.86 g/mol.
The molecular framework of 4-(4-Chlorophenyl)-2-[(E)-2-[(4-methoxyphenyl)amino]ethenyl]-6-methylpyridine-3,5-dicarbonitrile (C23H17ClN4O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures 4-(4-Chlorophenyl)-2-[(E)-2-[(4-methoxyphenyl)amino]ethenyl]-6-methylpyridine-3,5-dicarbonitrile 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.
