Description

Compared with other compounds in its class, the molecular weight of 312.58 g/mol gives 5,6-Dichloro-2-(6-chloropyridin-3-yl)-1-methyl-1H-1,3-benzodiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 5,6-Dichloro-2-(6-chloropyridin-3-yl)-1-methyl-1H-1,3-benzodiazole (CAS 337920-75-9), a certified reference material (molecular formula C13H8Cl3N3, MW 312.58 g/mol) for analytical method development and quality control.

Based on its molecular formula C13H8Cl3N3, 5,6-Dichloro-2-(6-chloropyridin-3-yl)-1-methyl-1H-1,3-benzodiazole contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 312.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
