Chemical Structure
Description
The occurrence of 1-Methyl-3-phenyl-N-[3-(trifluoromethyl)phenyl]-1H-thieno[2,3-c]pyrazole-5-carboxamide is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-Methyl-3-phenyl-N-[3-(trifluoromethyl)phenyl]-1H-thieno[2,3-c]pyrazole-5-carboxamide (CAS 478066-99-8), a certified reference material (molecular formula C20H14F3N3OS, MW 401.40 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 1-Methyl-3-phenyl-N-[3-(trifluoromethyl)phenyl]-1H-thieno[2,3-c]pyrazole-5-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 401.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
