Description

Compared with other compounds in its class, the molecular weight of 283.11 g/mol gives (E)-3-[5-(2,5-dichlorophenyl)-2-furyl]-2-propenoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(E)-3-[5-(2,5-dichlorophenyl)-2-furyl]-2-propenoic acid (CAS 329795-33-7) is a high-purity analytical reference standard with the molecular formula C13H8Cl2O3 and a molecular weight of 283.11 g/mol.

(E)-3-[5-(2,5-dichlorophenyl)-2-furyl]-2-propenoic acid (C13H8Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
