CATO supplies 1-Benzyl-5-chloro-2-(6-chloropyridin-3-yl)-1H-1,3-benzodiazole (CAS 400075-97-0), a certified reference material (molecular formula C19H13Cl2N3, MW 354.23 g/mol) for analytical method development and quality control.
1-Benzyl-5-chloro-2-(6-chloropyridin-3-yl)-1H-1,3-benzodiazole (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.
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.
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.
