p-Cresol is a major component in pig odor. [11] Temporal glands secretion examination showed the presence of phenol and p-cresol during musth in male elephants. [12] [13] It is one of the very few compounds to attract the orchid bee Euglossa cyanura and has been used to capture and study the species.
In its chemical structure, a molecule of cresol has a methyl group substituted onto the ring of phenol. There are three forms of cresol: ortho-cresol (o-cresol), meta-cresol (m-cresol), and para-cresol (p-cresol). These forms occur separately or as a mixture, which can also be called cresol or more specifically, tricresol.
[16] o-Cresol may be a less sensitive marker of toluene exposure than hippuric acid. [18] o-Cresol excretion may be an unreliable method for measuring toluene exposure because o-cresol makes up <1% of total toluene elimination. [14] Benzylmercapturic acid, a minor metabolite of toluene, is produced from benzaldehyde. [19]
Cresol (m-, p-, and o-), phenol, guaiacol, and xylenol (1,3,4- and 1,3,5-) all are acute aquatic hazards [citation needed] prior to going through chemical reactions with the sediments. Alkylation reactions allows for the compounds to transition into more toxic compounds [ citation needed ] with the addition of R-groups to the major compounds ...

p-Chlorocresol, or 4-chloro-3-methylphenol (ClC 6 H 3 CH 3 OH), also known as p-chloro-m-cresol, is a potent disinfectant and antiseptic. [1] It appears as a pinkish white crystalline solid. [2] It is also used as a preservative [3] in cosmetics and medicinal products for both humans and animals. It is used as an active ingredient in some ...
The systematic name of this enzyme class is 4-cresol:acceptor oxidoreductase (methyl-hydroxylating). Other names in common use include p-cresol–(acceptor) oxidoreductase (hydroxylating), and p-cresol methylhydroxylase. This enzyme participates in toluene and xylene degradation. It has 2 cofactors: FAD, and Cytochrome c.
The 2,6-diformyl derivative of p-cresol is the most common isomer and is a white solid at room temperature. Diformylcresol condenses with amines to give diimines that are widely studied as binucleating ligands. [2] [3]
