3-[3,5-Bis(trifluoromethyl)pyridin-2-yl]-1-(4-methylbenzenesulfonyl)urea (CAS 866043-24-5) is a high-purity analytical reference standard with the molecular formula C15H11F6N3O3S and a molecular weight of 427.32 g/mol.
3-[3,5-Bis(trifluoromethyl)pyridin-2-yl]-1-(4-methylbenzenesulfonyl)urea (C15H11F6N3O3S) contains a nitrogen-containing heterocyclic scaffold, 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.
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.
