General description

4-tert-Butylcatechol,in the presence of O2 catalyzed by tyrosinase, yields 4-tert-butyl-o-benzoquinone. Electrochemical oxidation of 4-tert-Butylcatechol in the presence of 4-hydroxycoumarin as nucleophile has been studied using cyclic voltammetry and controlled-potential coulometry. It undergoes electrochemical trimerization via anodic oxidation and mechanism of trimerization has been studied using cyclic voltammetry and controlled-potential coulometry.

Application

  • Antioxidant source for radical reactions: Research identified 4-tert-Butylcatechol as a viable source of hydrogen atoms in radical reactions, specifically in deiodination processes, expanding its utility in synthetic organic chemistry (Povie et al., 2016).

Polyphenol oxidase (PPO) has been extracted from both soluble and particulate fractions of loquat fruit (Eriobotrya japonica Lindl. cv. Algerie). The soluble PPO (20% of total activity) was partially purified 3.3-fold after ammonium sulfate fractionation being in its active state.
