1-(2,4-Difluorophenyl)-3-(1-methyl-1H-indol-3-yl)urea (CAS 899753-70-9) is a high-purity analytical reference standard with the molecular formula C16H13F2N3O and a molecular weight of 301.29 g/mol.
1-(2,4-Difluorophenyl)-3-(1-methyl-1H-indol-3-yl)urea (C16H13F2N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
