Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula C 6 H 5 OH. [5] It is a white crystalline solid that is volatile . The molecule consists of a phenyl group ( −C 6 H 5 ) bonded to a hydroxy group ( −OH ).
C 6-C 7-C 6 Diarylheptanoids are not included in this Harborne classification.. They can also be classified on the basis of their number of phenol groups. They can therefore be called simple phenols or monophenols, with only one phenolic group, or di-(bi-), tri-and oligophenols, with two, three or several phenolic groups respectively.
Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule. Phenol – the simplest of the phenols Chemical structure of salicylic acid, the active metabolite of aspirin. Phenols are both synthesized industrially and produced by plants and microorganisms. [2]
Thymol (also known as 2-isopropyl-5-methylphenol, IPMP), C 10 H 14 O, is a natural monoterpenoid phenol derivative of p-Cymene, isomeric with carvacrol.It occurs naturally in the oil of thyme, and it is extracted from Thymus vulgaris (common thyme), ajwain, [4] and various other plants as a white crystalline substance of a pleasant aromatic odor and strong antiseptic properties.
Chloroxylenol, also known as para-chloro-meta-xylenol (PCMX), is a chlorine substituted phenol with a white to off-white appearance and a phenolic odor.. The discovery of chloroxylenol was the result of efforts to produce improved antiseptics that began at the end of the 1800s, when scientists gradually realized that more substituted and more lipophilic phenols are less toxic, less irritant ...
Geosmin (/ dʒ i ˈ ɒ z m ɪ n / jee-OZ-min) is an irregular sesquiterpenoid with a distinct earthy or musty odor, which most people can easily smell. The geosmin odor detection threshold in humans is very low, ranging from 0.006 to 0.01 micrograms per liter in water. [1]
