Based on its molecular formula C18H27NO2, 974109G71I 5232-99-5 Ethyl 2-cyano-3,3-diphenylacrylate Ethyl 2-cyano-3,3-diphenyl-2-propenoate Etocrylene Etocrylene [USAN] 2-Propenoic acid, 2-cyano-3,3-diphenyl-, ethyl ester UV absorber-2 Etocrilene [INN] Acrylic acid, 2-cyano-3,3-diphenyl-, ethyl ester (8CI) Acrylonitrile, 3,3-dicyclopropyl-2-(ethoxycarbonyl)- Etocrilene 4-09-00-03640 (Beilstein Handbook Reference) Acrylonitrile, beta, beta-biscyclopropyl-,alpha-carbethoxy- Acrylonitrile, beta,beta-biscyclopropyl-alpha-carbethoxy- BRN 1885803 alpha-Carbethoxy-beta,beta-biscyclopropyl acrylonitrile CE 2 alpha-Cyano-beta-phenylcinnamic acid, ethyl ester EINECS 226-029-0 Ethyl alpha-cyan-beta,beta-diphenylacrylate Ethyl alpha-cyano-beta,beta-diphenylacrylate Ethyl (diphenylmethylene)cyanoacetate Etocrileno [INN-Spanish] Etocrilenum [INN-Latin] NSC 52678 USAF A-15972 Uvinul N 35 HSDB 7218 Etocrileno Etocrilenum UNII-974109G71I EC 226-029-0 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 289.41 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).
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.
