Chemical Structure

1-methyl-1H-1,2,3-triazole-4-carbonitrile CAS 1142927-01-2 chemical structure

Description

Owing to a nitrile group, 1-methyl-1H-1,2,3-triazole-4-carbonitrile is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 108.10 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).

1-methyl-1H-1,2,3-triazole-4-carbonitrile (CAS 1142927-01-2), molecular formula C4H4N4 and molecular weight 108.10 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), 1-methyl-1H-1,2,3-triazole-4-carbonitrile 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.
