3-Ethylphenol Explained

3-Ethylphenol is an organic compound with the formula C2H5C6H4OH. It is one of three isomeric ethylphenols. A colorless liquid, it occurs as an impurity in xylenols and as such is used in the production of commercial phenolic resins.

Niche use and occurrence

3-Ethylphenol is found in urine samples of female elephants.[1]

It is used as a photographic chemical intermediate and an intermediate for the cyan coupler of photographic paper.[2] It's a tsetse fly attractant. Therefore, it's a kairomone.[3]
