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]
2,3-Dichlorophenol; 2,4-Dichlorophenol; 2,5-Dichlorophenol; 2,6-Dichlorophenol; 3,4-Dichlorophenol; 3,5-Dichlorophenol; Dichlorophenols are used as intermediates in the manufacture of more complex chemical compounds, including the common herbicide 2,4-dichlorophenoxyacetic acid (2,4-D). [1]
Triphenylmethanol (also known as triphenylcarbinol and TrOH) is an organic compound. It is a white crystalline solid that is insoluble in water and petroleum ether , but well soluble in ethanol , diethyl ether , and benzene .
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 ...
2,4,6-Trichlorophenol, for example, has two chlorine atoms in the ortho positions and one chlorine atom in the para position. There are six different isomers: 2,3,4-Trichlorophenol
(C 6 H 5) 3 CCl + 2 Na → (C 6 H 5) 3 CNa + NaCl. Reaction with silver hexafluorophosphate gives triphenylmethyl hexafluorophosphate. Trityl chloride reacts with zinc in nonpolar solvents (e.g. benzene) to form Gomberg's dimer. [5] 2 (C 6 H 5) 3 CCl + Zn → ((C 6 H 5) 3 C) 2 + ZnCl 2
