Chemical Structure

2-Amino-1-methyl-1H-imidazol-5(4H)-one CAS 34293-24-8 chemical structure

Description

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.

2-Amino-1-methyl-1H-imidazol-5(4H)-one (CAS 34293-24-8), molecular formula C4H7N3O and molecular weight 113.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Amino-1-methyl-1H-imidazol-5(4H)-one (C4H7N3O) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
