Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-(2-(5-Cyclopropyl-3-(thiophen-2-yl)-1H-pyrazol-1-yl)ethyl)-3-(2,6-difluorophenyl)urea (CAS 1797245-09-0), a certified reference material (molecular formula C19H18F2N4OS, MW 388.43 g/mol) for analytical method development and quality control.
1-(2-(5-Cyclopropyl-3-(thiophen-2-yl)-1H-pyrazol-1-yl)ethyl)-3-(2,6-difluorophenyl)urea (C19H18F2N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
