2,4-Di-tert-butylphenol (2,4-DTBP) is a white solid with a phenolic odour. It is primarily used as a raw material for the production of several commercially important antioxidants and phenolic benzotriazole-type UV absorbers. It also finds use as a starting material in the synthesis of agrochemicals, fragrances and catalysts (i.e. Jacobsen's catalyst).

Despite its toxicity against most tested organisms, it is made by a wide range of living organisms: 169 species of bacteria, fungi, plants, and animals.
