Chemical Structure

N-(4,5-dimethyl-1H-imidazol-2-yl)acetamide CAS 40639-97-2 chemical structure

Description

N-(4,5-dimethyl-1H-imidazol-2-yl)acetamide (CAS 40639-97-2) is a high-purity analytical reference standard with the molecular formula C7H11N3O and a molecular weight of 153.18 g/mol.

Structurally, N-(4,5-dimethyl-1H-imidazol-2-yl)acetamide (C7H11N3O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 153.18 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
