Chemical Structure

2-Amino-3,5-dihydro-4H-imidazol-4-one CAS 503-86-6 chemical structure

Description

CATO supplies 2-Amino-3,5-dihydro-4H-imidazol-4-one (CAS 503-86-6), a certified reference material (molecular formula C3H5N3O, MW 99.09 g/mol) for analytical method development and quality control.

Structurally, 2-Amino-3,5-dihydro-4H-imidazol-4-one (C3H5N3O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 99.09 g/mol, it falls into the low-molecular-weight range. 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.

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.
