Chemical Structure
Description
CATO supplies 2-(4-(Diphenylamino)benzylidene)malononitrile (CAS 40703-88-6), a certified reference material (molecular formula C22H15N3, MW 321.37 g/mol) for analytical method development and quality control.
The molecular framework of 2-(4-(Diphenylamino)benzylidene)malononitrile (C22H15N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
