Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 196.20 g/mol gives Ethyl 4-(furan-2-yl)-3-oxobutanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 4-(furan-2-yl)-3-oxobutanoate (CAS 577776-75-1) is a high-purity analytical reference standard with the molecular formula C10H12O4 and a molecular weight of 196.20 g/mol.
Ethyl 4-(furan-2-yl)-3-oxobutanoate (C10H12O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
