2-Methyl-4,7-di(thiophen-2-yl)-2H-benzo[d][1,2,3]triazole CAS 1355346-56-3

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 2-Methyl-4,7-di(thiophen-2-yl)-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 297.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

2-Methyl-4,7-di(thiophen-2-yl)-2H-benzo[d][1,2,3]triazole (CAS 1355346-56-3), molecular formula C15H11N3S2 and molecular weight 297.40 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 2-Methyl-4,7-di(thiophen-2-yl)-2H-benzo[d][1,2,3]triazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
