1-(4-Chlorobenzyl)-2-(2-chloropyridin-3-yl)-1H-benzo[d]imidazole CAS 338411-33-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Chlorobenzyl)-2-(2-chloropyridin-3-yl)-1H-benzo[d]imidazole.

1-(4-Chlorobenzyl)-2-(2-chloropyridin-3-yl)-1H-benzo[d]imidazole (CAS 338411-33-9), molecular formula C19H13Cl2N3 and molecular weight 354.23 g/mol, is a CATO reference standard with documented purity and traceability.

1-(4-Chlorobenzyl)-2-(2-chloropyridin-3-yl)-1H-benzo[d]imidazole (C19H13Cl2N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
