Phenol – the simplest of the phenols Chemical structure of salicylic acid, the active metabolite of aspirin Chemical structure of aloe emodin, a diphenol Quercetin, a typical flavonoid, is a polyphenol Tannic acid, a typical polyphenol of indeterminate structure Lignin, is around 25% of the composition of wood This structure is repeated many ...
Phenol is also a versatile precursor to a large collection of drugs, most notably aspirin but also many herbicides and pharmaceutical drugs. Phenol is a component in liquid–liquid phenol–chloroform extraction technique used in molecular biology for obtaining nucleic acids from tissues or cell culture samples.
The simplest is phenol, C 6 H 5 OH. 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 ...
In 2015, Interpol and the World Anti-Doping Agency released an orange notice warning of the dangers of DNP. [25] In 1941, the Eastman Kodak Company, a bulk distributor of DNP, was investigated after some of its product was found in illegal diet pills. [39] Nicholas Bachynsky, a Texas physician, provided the drug to patients under the name ...
The name derives from the Ancient Greek word πολύς (polus, meaning "many, much") and the word ‘phenol’ which refers to a chemical structure formed by attachment of an aromatic benzenoid ring to a hydroxyl (-OH) group (hence the -ol suffix). The term "polyphenol" has been in use at least since 1894. [4]
It can also be used to produce tris(4-nonyl-phenyl) phosphite (TNPP), which is an antioxidant used to protect polymers, such as rubber, Vinyl polymers, polyolefins, and polystyrenics in addition to being a stabilizer in plastic food packaging. Barium and calcium salts of nonylphenol are also used as heat stabilizers for polyvinyl chloride (PVC ...
Foodborne illness (also known as foodborne disease and food poisoning) [1] is any illness resulting from the contamination of food by pathogenic bacteria, viruses, or parasites, [2] as well as prions (the agents of mad cow disease), and toxins such as aflatoxins in peanuts, poisonous mushrooms, and various species of beans that have not been boiled for at least 10 minutes.
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 lipophylic phenols are less toxic, less irritant ...
