Diphenol
Diphenol may refer to: * Benzenediols * Bisphenols * Dihydroxybiphenyls * Certain polyphenol Polyphenols () are a large family of naturally occurring organic compounds characterized by multiples of phenol units. They are abundant in plants and structurally diverse. Polyphenols include flavonoids, tannic acid, and ellagitannin, some o ...s (those with 2 phenolic groups) {{Short pages monitor ...

Benzenediol
In organic chemistry, dihydroxybenzenes (benzenediols) are organic compounds in which two hydroxyl groups () are Arene substitution reaction, substituted onto a benzene ring (). These aromatic compounds are classed as phenols. There are three structural isomers: 1,2-dihydroxybenzene (the ''ortho'' isomer) is commonly known as catechol, 1,3-dihydroxybenzene (the ''meta'' isomer) is commonly known as resorcinol, and 1,4-dihydroxybenzene (the ''para'' isomer) is commonly known as hydroquinone. : All three of these compounds are colorless to white granular solids at room temperature and pressure, but upon exposure to oxygen they may darken. All three isomers have the chemical formula . Similar to other phenols, the hydroxyl groups on the aromatic ring of a benzenediol are weakly acidic. Each benzenediol can lose an from one of the hydroxyls to form a type of phenolate ion. The Dakin oxidation is an organic redox reaction in which an ''ortho''- or ''para''-hydroxylated phenyl alde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bisphenol
The bisphenols () are a group of chemical compounds related to diphenylmethane. Most are based on two hydroxyphenyl functional groups linked by a methylene bridge. Exceptions include bisphenol S, P, and M. "Bisphenol" is a common name; the letter following denotes the variant, which depends on the additional substituents. Bisphenol A is the most popular representative of the group, often simply called "bisphenol".. List Health effects Bisphenols A (BPA), F (BPF) and S (BPS) have been shown to be endocrine disruptors. Due to its high production volumes, BPA has been characterised as a "pseudo-persistent" chemical, leading to its spreading and potential accumulation in a variety of environmental matrices, even though it has a fairly short half-life Half-life (symbol ) is the time required for a quantity (of substance) to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dihydroxybiphenyl
Dihydroxybiphenyl (as known as biphenol) may refer to: * 2,2'-Dihydroxybiphenyl * 2,3'-Dihydroxybiphenyl * 2,4'-Dihydroxybiphenyl * 3,3'-Dihydroxybiphenyl * 3,4'-Dihydroxybiphenyl * 4,4'-Dihydroxybiphenyl {{chemistry index ...
