Description

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.

(E)-Ethyl 2-(5-ethoxydihydrofuran-3(2H)-ylidene)acetate (CAS 119614-41-4), molecular formula C10H16O4 and molecular weight 200.23 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H16O4, (E)-Ethyl 2-(5-ethoxydihydrofuran-3(2H)-ylidene)acetate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 200.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
