2-Benzyl-4,7-di(thiophen-2-yl)-2H-benzo[d][1,2,3]triazole CAS 1271731-83-9

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.

2-Benzyl-4,7-di(thiophen-2-yl)-2H-benzo[d][1,2,3]triazole (CAS 1271731-83-9) is a high-purity analytical reference standard with the molecular formula C21H15N3S2 and a molecular weight of 373.49 g/mol.

The molecular framework of 2-Benzyl-4,7-di(thiophen-2-yl)-2H-benzo[d][1,2,3]triazole (C21H15N3S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
