Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 3-{1-[(2,6-dichlorophenyl)methyl]-6-oxo-1,6-dihydropyridin-3-yl}-1-(3,4-difluorophenyl)urea (CAS 338784-71-7), a certified reference material (molecular formula C19H13Cl2F2N3O2, MW 424.23 g/mol) for analytical method development and quality control.
3-{1-[(2,6-dichlorophenyl)methyl]-6-oxo-1,6-dihydropyridin-3-yl}-1-(3,4-difluorophenyl)urea (C19H13Cl2F2N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
