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]
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 .
2,6-Dichloro-4-nitroaniline is an organic compound with the formula O 2 NC 6 H 2 Cl 2 NH 2. It is the most widely discussed isomer of dichloronitroaniline, mainly as a precursor to the azo dye disperse brown 1. It is prepared by treatment of 4-nitroaniline with a mixture of hydrochloric acid and hydrogen peroxide (a source of chlorine). [3] [4]
C 6 H 5 OH + 2 CH 2 =C(CH 3) 2 → ((CH 3) 3 C) 2 C 6 H 3 OH. In this way, approximately 2.5M kg/y are produced. [2] Alkylation of phenol usually favours the para-position, and a strong lewis acid such as the Al 3+ ion is necessary to give selective ortho‑alkylation. [3] [4] If a conventional brønsted acid is used then 2,4-di-tert ...
