Chemical Structure

1-Butyl-3-methyl-1H-imidazol-2(3H)-one CAS 586965-19-7 chemical structure

Description

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.

1-Butyl-3-methyl-1H-imidazol-2(3H)-one (CAS 586965-19-7) is a high-purity analytical reference standard with the molecular formula C8H14N2O and a molecular weight of 154.21 g/mol.

Structurally, 1-Butyl-3-methyl-1H-imidazol-2(3H)-one (C8H14N2O) 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 154.21 g/mol, it falls into the medium-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).

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.
