Description

General description

tert-Butylhydroquinone (TBHQ) is a phenolic antioxidant. TBHQ is frequently used as a food preservative. In low concentrations it shows cytoprotective qualities while at higher concentrations it exhibits cytotoxic behavior.[1]

Application

TBHQ was used to study the inactivation of barotolerant strains of Listeria monocytogenes and Escherichia coli.[2] Environment friendly electrode materials for supercapacitors were attained by decorating the surface of graphene nanosheets with TBHQ.[3]
