Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 288.22 g/mol gives Ethyl 2,4-dioxo-4-[2-(trifluoromethyl)phenyl]butanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2,4-dioxo-4-[2-(trifluoromethyl)phenyl]butanoate (CAS 737772-44-0) is a high-purity analytical reference standard with the molecular formula C13H11F3O4 and a molecular weight of 288.22 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, Ethyl 2,4-dioxo-4-[2-(trifluoromethyl)phenyl]butanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
