The reaction of 4-tert-butyl-1,2-benzoquinone (BQ) with 4-amino-N,N- diethylaniline (ADA) produces a stable blue adduct with λ(max) 625 nm (ε 11,120 M-1 cm-1). This makes the reaction a sensitive analytical tool, suitable for the detection and spectrophotometric determination of this quinone even in the presence of biological compounds. The adduct was identified as 3-tert-butyl-4-(4'-diethylamino)phenylimino-6-hydroxycyclohexa- 2,5-dien-1-one. (C) 2000 Elsevier Science Ltd.

Abstract
The reaction of 4-tert-butyl-1,2-benzoquinone (BQ) with 4-amino-N,N- diethylaniline (ADA) produces a stable blue adduct with λ(max) 625 nm (ε 11,120 M-1 cm-1). This makes the reaction a sensitive analytical tool, suitable for the detection and spectrophotometric determination of this quinone even in the presence of biological compounds. The adduct was identified as 3-tert-butyl-4-(4'-diethylamino)phenylimino-6-hydroxycyclohexa- 2,5-dien-1-one.
