2,6-Dichlorophenolindophenol (DCPIP, DCIP or DPIP) is a chemical compound used as a redox dye. When oxidized, DCPIP is blue with a maximal absorption at 600 nm; when reduced, DCPIP is colorless. DCPIP can be used to measure the rate of photosynthesis. It is part of the Hill reagents family. When exposed to light in a photosynthetic system, the ...
2,6-Dichlorophenol is a compound with formula C 6 H 3 Cl 2 OH. It is one of the six isomers of dichlorophenol. It is a colorless solid. Its pK a is 6.78, which is about 100x more acidic than 2-chlorophenol (8.52) and 1000x more acidic than phenol itself (9.95). [3]
Chemical structure of 2,4-dichlorophenol. Dichlorophenols (DCPs) are any of several chemical compounds which are derivatives of phenol containing two chlorine atoms. There are six isomers: 2,3-Dichlorophenol; 2,4-Dichlorophenol; 2,5-Dichlorophenol; 2,6-Dichlorophenol; 3,4-Dichlorophenol; 3,5-Dichlorophenol
Melting point: 109 to 112 °C (228 to 234 °F; 382 to 385 K) ... It may be prepared by the reaction of triphenylmethanol with acetyl chloride, ... 2 (C 6 H 5) 3 CCl ...
Its sodium salt can be prepared from the chloride: [6] (C 6 H 5) 3 CCl + 2 Na → (C 6 H 5) 3 CNa + NaCl. The use of tritylsodium as a strong, non-nucleophilic base has been eclipsed by the popularization of butyllithium and related strong bases. The unmodified anion is red, and can be used as an indicator in acid–base titrations. Derived ...
Triphenylmethanol features three phenyl (Ph) rings and an alcohol group bound to a central tetrahedral carbon atom. All three C–Ph bonds are typical of sp 3-sp 2 carbon-carbon bonds with lengths of approximately 1.47 Å, while the C–O bond length is approximately 1.42 Å.
2,6-Dichloroquinone-4-chloroimide (Gibbs reagent) is an organic compound used as an colorimetric indicator to detect phenolic compounds. [1] Upon reaction with phenol itself, 2,6-dichlorophenolindophenol is formed, [ 2 ] a chemical that is used as a redox indicator .
