Description and Uses

2,5-Di-tert-butylhydroquinone, also known as 2,5-TBHQ or DTBHQ, belongs to the class of organic compounds known as phenylpropanes. These are organic compounds containing a phenylpropane moiety. It is a phenol derivative containing 2 phenol groups and 2 alkyl groups, each consisting of three methyl groups.

2,5-Di-tert-butylhydroquinone is the oxidation substrate used to measure the catalytic activity of the copper(II) enzyme-like catalysts.
