4,7-Bis(5-bromothiophen-2-yl)-2-octyl-2H-benzo[d][1,2,3]triazole CAS 1254062-39-9

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.

4,7-Bis(5-bromothiophen-2-yl)-2-octyl-2H-benzo[d][1,2,3]triazole (CAS 1254062-39-9), molecular formula C22H23Br2N3S2 and molecular weight 553.38 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution, 4,7-Bis(5-bromothiophen-2-yl)-2-octyl-2H-benzo[d][1,2,3]triazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 553.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
