2177-18-6 Acrylic acid, vinyl ester (6CI,7CI,8CI) 2-Propenoic acid, ethenyl ester Vinyl acrylate Acrylic acid vinyl ester CCRIS 7746 EINECS 218-538-1 Ethenyl 2-propenoate (CAS 2177-18-6) is a high-purity analytical reference standard with the molecular formula C5H6O2 and a molecular weight of 98.10 g/mol.
2177-18-6 Acrylic acid, vinyl ester (6CI,7CI,8CI) 2-Propenoic acid, ethenyl ester Vinyl acrylate Acrylic acid vinyl ester CCRIS 7746 EINECS 218-538-1 Ethenyl 2-propenoate (C5H6O2) contains a carboxylic acid 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).
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.
