Chemical Structure
Description
(4-Methyl-2,5-dioxoimidazolidin-4-yl)methanesulfonyl chloride (CAS 674348-00-6), molecular formula C5H7ClN2O4S and molecular weight 226.64 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-Methyl-2,5-dioxoimidazolidin-4-yl)methanesulfonyl chloride (C5H7ClN2O4S) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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.
