The occurrence of 2-Butenedioic acid (2Z)-, 1-(2-ethylhexyl) ester, polymer with ethenyl acetate and 2,5-furandione is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Butenedioic acid (2Z)-, 1-(2-ethylhexyl) ester, polymer with ethenyl acetate and 2,5-furandione (CAS 63528-94-9), a certified reference material (molecular formula C12H20O4C4H2O3C4H6O2, MW 412.44 g/mol) for analytical method development and quality control.
Based on its molecular formula C12H20O4C4H2O3C4H6O2, 2-Butenedioic acid (2Z)-, 1-(2-ethylhexyl) ester, polymer with ethenyl acetate and 2,5-furandione contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 412.44 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).
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.
