General description

4-Methylphenol is an isomer of the phenolic compound, named cresol. It can be formed via action of colonic bacteria on tyrosine and phenylalanine in human body. It can act like a an odorant and a component of human sweat, which can have the tendency to attract female Anopheles mosquitoes, the world′s most important vector of Plasmodium falciparum malaria.

Application

4-Methylphenol can be used in the preparation of toluene via hydrodeoxygenation in the presence of cobalt dispersed on molybdenum disulfide monolayers as catalyst.

Cholesterol ester (ChE) and triacylglycerol (TG) hydroperoxides in human plasma were determined by high-performance liquid chromatography with postcolumn detection with diphenyl-1-pyrenylphosphine. Human plasma was extracted once with n-hexane. 2,6-Di-tert.-butyl-4-methylphenol and N-stearylcinnamide were added to human plasma before extraction as an
