Chemical Structure

4-(4,5-Dihydro-1H-imidazol-2-yl)-4H-1,2,4-triazole CAS 777820-68-5 chemical structure

Description

CATO supplies 4-(4,5-Dihydro-1H-imidazol-2-yl)-4H-1,2,4-triazole (CAS 777820-68-5), a certified reference material (molecular formula C5H7N5, MW 137.14 g/mol) for analytical method development and quality control.

Owing to a nitrile group, 4-(4,5-Dihydro-1H-imidazol-2-yl)-4H-1,2,4-triazole is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.14 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).

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), 4-(4,5-Dihydro-1H-imidazol-2-yl)-4H-1,2,4-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.
