Chemical Structure
Description
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.
CATO supplies 1-(2,5-Dioxoimidazolidin-4-yl)urea 2-acetamido-4-(methylthio)butanoate (CAS 4207-40-3), a certified reference material (molecular formula C7H13NO3SC4H6N4O3, MW 349.36 g/mol) for analytical method development and quality control.
1-(2,5-Dioxoimidazolidin-4-yl)urea 2-acetamido-4-(methylthio)butanoate (C7H13NO3SC4H6N4O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
