Chemical Structure
Description
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.
CATO supplies 1-[(2,4-Dichlorophenyl)methyl]-3-(1-{1-[(2,4-dichlorophenyl)methyl]-1H-indol-3-yl}ethenyl)-1H-indole (CAS 338777-63-2), a certified reference material (molecular formula C32H22Cl4N2, MW 576.34 g/mol) for analytical method development and quality control.
The molecular framework of 1-[(2,4-Dichlorophenyl)methyl]-3-(1-{1-[(2,4-dichlorophenyl)methyl]-1H-indol-3-yl}ethenyl)-1H-indole (C32H22Cl4N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
