1-(4-Bromo-2-(trifluoromethoxy)phenyl)-3-(1-(tetrahydro-2H-pyran-4-yl)-1H-pyrazol-4-yl)thiourea CAS 1858250-66-4

Description

The occurrence of 1-(4-Bromo-2-(trifluoromethoxy)phenyl)-3-(1-(tetrahydro-2H-pyran-4-yl)-1H-pyrazol-4-yl)thiourea is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(4-Bromo-2-(trifluoromethoxy)phenyl)-3-(1-(tetrahydro-2H-pyran-4-yl)-1H-pyrazol-4-yl)thiourea (CAS 1858250-66-4), molecular formula C16H16BrF3N4O2S and molecular weight 465.29 g/mol, is a CATO reference standard with documented purity and traceability.

1-(4-Bromo-2-(trifluoromethoxy)phenyl)-3-(1-(tetrahydro-2H-pyran-4-yl)-1H-pyrazol-4-yl)thiourea (C16H16BrF3N4O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine 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. 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).
