Chemical Structure
Description
The occurrence of 7,9-Dimethyl-2-(trifluoromethyl)-1,2-dihydro-4H-thieno[2,3-c]chromen-4-one is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
7,9-Dimethyl-2-(trifluoromethyl)-1,2-dihydro-4H-thieno[2,3-c]chromen-4-one (CAS 380565-51-5), molecular formula C14H11F3O2S and molecular weight 300.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, 7,9-Dimethyl-2-(trifluoromethyl)-1,2-dihydro-4H-thieno[2,3-c]chromen-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.30 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
