Chemical Structure
Description
Based on its molecular formula C11H18O3, 5396-89-4 F9S0XGV18X Benzyl acetoacetate Acetoacetic acid, benzyl ester (8CI) Butanoic acid, 3-oxo-, phenylmethyl ester Acetoacetic acid, benzyl ester AI3-06229 Benzyl acetylacetate Benzyl beta-ketobutyrate Benzyl 3-oxobutanoate EINECS 226-416-4 FEMA No. 2136 NSC 4391 Phenylmethyl 3-oxobutanoate UNII-F9S0XGV18X 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 198.26 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).
