Chemical Structure
Description
(2E)-2-(5-Acetylthiophen-2-yl)-3-(2,5-difluorophenyl)prop-2-enenitrile (CAS 478260-99-0), molecular formula C15H9F2NOS and molecular weight 289.30 g/mol, is a CATO reference standard with documented purity and traceability.
(2E)-2-(5-Acetylthiophen-2-yl)-3-(2,5-difluorophenyl)prop-2-enenitrile (C15H9F2NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
