Common Name2-Ethylphenol
Description2-ethylphenol, also known as phlorol or 1-ethyl-2-hydroxybenzene, is a member of the class of compounds known as 1-hydroxy-4-unsubstituted benzenoids. 1-hydroxy-4-unsubstituted benzenoids are phenols that are unsubstituted at the 4-position. 2-ethylphenol is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). 2-ethylphenol can be found in arabica coffee, which makes 2-ethylphenol a potential biomarker for the consumption of this food product. Ethylphenol may refer to: 2-Ethylphenol 3-Ethylphenol 4-Ethylphenol .
