1,2-Bis((1H-benzo[d][1,2,3]triazol-1-yl)methyl)benzene CAS 312323-71-0

Description

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.

1,2-Bis((1H-benzo[d][1,2,3]triazol-1-yl)methyl)benzene (CAS 312323-71-0), molecular formula C20H16N6 and molecular weight 340.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1,2-Bis((1H-benzo[d][1,2,3]triazol-1-yl)methyl)benzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
