Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 387.87 g/mol gives 5-(4-Cyanophenyl)-2,3-di-p-tolyl-2H-tetrazol-3-ium chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-(4-Cyanophenyl)-2,3-di-p-tolyl-2H-tetrazol-3-ium chloride (CAS 376591-03-6), a certified reference material (molecular formula C22H18N5Cl, MW 387.87 g/mol) for analytical method development and quality control.
The molecular framework of 5-(4-Cyanophenyl)-2,3-di-p-tolyl-2H-tetrazol-3-ium chloride (C22H18N5Cl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
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.
