2-Propenoic acid, ethyl ester, polymer with ethenylbenzene and N-(hydroxymethyl)-2-propenamide (C8H8C4H7NO2C5H8O2) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
2-Propenoic acid, ethyl ester, polymer with ethenylbenzene and N-(hydroxymethyl)-2-propenamide (CAS 25301-38-6) is a high-purity analytical reference standard with the molecular formula C8H8C4H7NO2C5H8O2 and a molecular weight of 305.37 g/mol.
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.
