Chemical Structure
Description
The occurrence of (4-chloro-2-fluorophenyl)(3-methylthiophen-2-yl)methanone is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4-chloro-2-fluorophenyl)(3-methylthiophen-2-yl)methanone (CAS 1249924-08-0), molecular formula C12H8ClFOS and molecular weight 254.71 g/mol, is a CATO reference standard with documented purity and traceability.
(4-chloro-2-fluorophenyl)(3-methylthiophen-2-yl)methanone (C12H8ClFOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. 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.
CATO manufactures (4-chloro-2-fluorophenyl)(3-methylthiophen-2-yl)methanone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
