Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, N-Ethyl-2-(2-((2-((4-fluorophenyl)amino)-2-oxoethyl)thio)-5-(hydroxymethyl)-1H-imidazol-1-yl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 366.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
N-Ethyl-2-(2-((2-((4-fluorophenyl)amino)-2-oxoethyl)thio)-5-(hydroxymethyl)-1H-imidazol-1-yl)acetamide (CAS 921547-30-0) is a high-purity analytical reference standard with the molecular formula C16H19FN4O3S and a molecular weight of 366.41 g/mol.
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.
