Chemical Structure
Description
1-[ethyl(methyl)carbamoyl]-3-methyl-1H-imidazol-3-ium iodide (C8H14N3OI) contains an amide group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
1-[ethyl(methyl)carbamoyl]-3-methyl-1H-imidazol-3-ium iodide (CAS 1091604-39-5) is a high-purity analytical reference standard with the molecular formula C8H14N3OI and a molecular weight of 295.12 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.
