Chemical Structure

1-Ethyl-4-tosyl-1,3-dihydro-2H-imidazol-2-one CAS 282109-01-7 chemical structure

Description

Based on its molecular formula C12H14N2O3S, 1-Ethyl-4-tosyl-1,3-dihydro-2H-imidazol-2-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 266.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 1-Ethyl-4-tosyl-1,3-dihydro-2H-imidazol-2-one (CAS 282109-01-7), a certified reference material (molecular formula C12H14N2O3S, MW 266.32 g/mol) for analytical method development and quality control.

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.
