Chemical Structure

4-Mercapto-1H-imidazole-5-carboximidhydrazide CAS 83256-03-5 chemical structure

Description

Owing to a nitrile group, sulfur-containing functionality, 4-Mercapto-1H-imidazole-5-carboximidhydrazide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 157.20 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).

CATO supplies 4-Mercapto-1H-imidazole-5-carboximidhydrazide (CAS 83256-03-5), a certified reference material (molecular formula C4H7N5S, MW 157.20 g/mol) for analytical method development and quality control.

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.

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.
