Abstract
The reaction of 4-tert-butyl-1,2-benzoquinone (BQ) with 4-amino-N,N-diethyl aniline (ADA) produces a stable blue adduct with lambda(max) 625 nm (epsilo n 11,120 M-1 cm(-1)). This makes the reaction a sensitive analytical tool, suitable for the detection and spectrophotometric determination of this qui none even in the presence of biological compounds. The adduct was identifie d as 3-tert-butyl-4-(4'-diethylamino)-phenylimino-6-hydroxycyclohexa-2,5-di en-1-one. (C) 2000 Elsevier Science Ltd. All rights reserved.
