General description

2,3-Dibromo-1,4-naphthoquinone is a 2,3-disubstituted 1,4-naphthoquinone. It is a plumbagin derivative and an acaricide. It undergoes photochemical reaction with 2-methoxy-1-alkene to yield derivatives of 2-(2-alkanonyl)-1,4-naphthoquinone.

Application

2,3-Dibromo-1,4-naphthoquinone may be used in the synthesis of 3-[3-(2-carboxy-ethylsulfanyl)-1,4-dioxo-1,4-dihydro-naphthalen-2-ylsulfanyl]-propionic acid and NSC 95397 (a protein tyrosine phosphatase antagonist).

As important secondary plant metabolites, naphthoquinones exhibit a wide range of biological activities. However, their potential as sustainable alternatives to synthetic acaricides has not been studied. This study for the first time investigates the acaricidal activity of naphthoquinones against Psoroptes
