(E)-4-(2-Trifluoromethyl-phenyl)-but-3-en-2-one 76293-37-3 9378AE C11H9F3O CAS 76293-37-3

Description

The occurrence of (E)-4-(2-Trifluoromethyl-phenyl)-but-3-en-2-one 76293-37-3 9378AE C11H9F3O is closely related to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (E)-4-(2-Trifluoromethyl-phenyl)-but-3-en-2-one 76293-37-3 9378AE C11H9F3O (CAS 76293-37-3), a certified reference material (molecular formula C11H9F3O, MW 214.18 g/mol) for analytical method development and quality control.

(E)-4-(2-Trifluoromethyl-phenyl)-but-3-en-2-one 76293-37-3 9378AE C11H9F3O (C11H9F3O) contains a hydroxyl group, an ether linkage, fluorine 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
