Owing to an amide group, a hydroxyl group, an ether linkage, 346440-54-8 8LC842A6QP 5-Benzyl-2-tert-butyl-3-methyl-4-imidazolidinone, (2S,5S)- UNII-8LC842A6QP Macmillan's imidazolidinone catalysts second generation catalyst [MI] 4-Imidazolidinone, 2-(1,1-dimethylethyl)-3-methyl-5-(phenylmethyl)-, (2S,5S)- (-)-(2S,5S)-5-Benzyl-2-tert-butyl-3-methylimidazolidin-4-one (2S,4S)-2-(1,1-Dimethylethyl)-3-methyl-5-(phenylmethyl)-4-imidazolidinone (2S,5S)-5-Benzyl-2-(tert-butyl)-3-methylimidazolidin-4-one Macmillan's imidazolidinone second generation catalyst is typically white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 252.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
