Based on its molecular formula C25H42N2O4, 28768-32-3 2I8ZB2RX2U Tetraglycidyl-4,4'-methylene dianiline 4,4'-Methylenebis(N,N-bis(2,3-epoxypropyl)aniline) 2-Oxiranemethanamine, N,N'-(methylenedi-4,1-phenylene)bis(N-(2-oxiranylmethyl)- Oxiranemethanamine, N,N'-(methylenedi-4,1-phenylene)bis(N-(oxiranylmethyl)- EINECS 249-204-3 4,4'-Methylenebis(diglycidyl aniline) UNII-2I8ZB2RX2U EC 249-204-3 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 434.61 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).
