(E)-3-[5-(3-chloro-4-methoxyphenyl)-2-furyl]-2-propenoic acid CAS 773130-07-7

Description

Compared with other compounds in its class, the molecular weight of 278.69 g/mol gives (E)-3-[5-(3-chloro-4-methoxyphenyl)-2-furyl]-2-propenoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (E)-3-[5-(3-chloro-4-methoxyphenyl)-2-furyl]-2-propenoic acid (CAS 773130-07-7), a certified reference material (molecular formula C14H11ClO4, MW 278.69 g/mol) for analytical method development and quality control.

(E)-3-[5-(3-chloro-4-methoxyphenyl)-2-furyl]-2-propenoic acid (C14H11ClO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
