Chemical Structure
Description
Ethyl (Z)-2-(ethoxymethylene)-4,4,4-trifluoro-3-oxobutanoate (CAS 1048670-08-1) is a high-purity analytical reference standard with the molecular formula C9H11F3O4 and a molecular weight of 240.18 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Ethyl (Z)-2-(ethoxymethylene)-4,4,4-trifluoro-3-oxobutanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.18 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.
