Chemical Structure

2-Methyl-1H-imidazole-4-carbothioamide CAS 129486-91-5 chemical structure

Description

2-Methyl-1H-imidazole-4-carbothioamide (CAS 129486-91-5), molecular formula C5H7N3S and molecular weight 141.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, sulfur-containing functionality, 2-Methyl-1H-imidazole-4-carbothioamide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.19 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), 2-Methyl-1H-imidazole-4-carbothioamide 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.
