Ethylphenol
Ethylphenol may refer to: * 2-Ethylphenol * 3-Ethylphenol * 4-Ethylphenol * Ethyl phenyl ether Ethyl phenyl ether (or phenetole) is an organic compound that belongs to a class of compounds called ethers. Ethyl phenyl ether has the same properties as some other ethers, such as volatility, explosive vapors, and the ability to form peroxides. ... (''O''-ethylphenol) {{Short pages monitor ...

4-Ethylphenol
Ethylphenol (4-EP) is an organic compound with the formula C2H5C6H4OH. It is one of three isomeric ethylphenols. A white solid, it occurs as an impurity in xylenols and as such is used in the production of some commercial phenolic resins. It is also a precursor to 4-vinylphenol. Natural occurrences In wine and beer, 4-EP is produced by the yeast ''Brettanomyces''. At concentrations greater than 140 μg/L (typical sensory threshold) it gives the wine aromas described as ''barnyard'', ''medicinal'', ''band-aids'', and ''mousy''. In certain Belgian beer styles, a high 4-EP level may be desirable; however, very high levels of the compound in wine can render it undrinkable. The level of 4-EP is roughly proportional to ''Brettanomyces'' concentration and activity, and can therefore be used as an indicator of the yeast's presence. There are significant differences between strains of ''Brettanomyces'' in their ability to produce 4-EP. 4-EP is also a component of castoreum, the e ...

3-Ethylphenol
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. It is used as a photographic chemical intermediate and an intermediate for the cyan coupler of photographic paper. It's a tsetse fly attractant. Therefore, it's a kairomone A kairomone (a coinage using the Greek καιρός ''opportune moment'', paralleling pheromone"kairomone, n.". OED Online. September 2012.

A colorless liquid, it occurs as an impurity in xylenols and as such is used in the production of commercial phenolic resin Phenol formaldehyde resins (PF) or phenolic resins (also infrequently called phenoplasts) are synthetic polymers obtained by the reaction of phenol or substituted phenol with formaldehyde. Used as the basis for Bakelite, PFs were the first commerc ...s. It is produced by ethylation of phenol using ethylene or ethanol in the presence of aluminium phenolate.
