Chemical Structure
Description
CATO supplies 3-(2-(3-Cyclohexylureido)thiazol-4-yl)-N-(3-fluorophenyl)propanamide (CAS 1091132-31-8), a certified reference material (molecular formula C19H23FN4O2S, MW 390.47 g/mol) for analytical method development and quality control.
3-(2-(3-Cyclohexylureido)thiazol-4-yl)-N-(3-fluorophenyl)propanamide (C19H23FN4O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
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.
