4-Nitrophenylsuccinic acid

2-(4-Nitrophenyl)succinic Acid can be useful in the preparation of aryl substituted 2-(4-nitrophenyl)-4-oxo-4-phenylbutanoates and 3-(4-nitrophenyl)-1-Ph-1,4-butanediols as inhibitors of rat liver microsomal retinoic acid metabolizing enzymes, preparation of 1-, and 3-substituted 3-(4'-aminophenyl)pyrrolidine-2,5-diones as selective inhibitors of aromatase, and preparation of diverse lactam carboxamides with potential transcription factor inhibitory activity.
