2,6-Dichloropyridine is a chloropyridine with the formula C 5 H 3 Cl 2 N. A white solid, it is one of six isomers of dichloropyridine . It serves as a precursor to the antibiotic enoxacin , [ 2 ] as well as the drug and anpirtoline and the antifungal liranaftate .
Clopyralid (3,6-dichloro-2-pyridinecarboxylic acid) is a selective herbicide used for control of broadleaf weeds, especially thistles and clovers.Clopyralid is in the picolinic acid family of herbicides, which also includes aminopyralid, picloram, triclopyr, and several less common herbicides.
Some dichlorotoluenes are precursors to commercial pesticides. 2,4-Dichlorotoluene is the precursor to pyrifenox, butafenacil, and the pyrazole derivatives pyrazoxyfen and [pyrazolynate]]. The 2,6 isomer is a precursor to dichlobenil (2,6-dichlorobenzonitrile). 3,5-Dichlorotoluene is used to prepare propyzamide. [2]
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 .
A low-pH throat lozenge containing dichlorobenzyl alcohol (1.2 mg) and amylmetacresol (0.6 mg) has been found to deactivate respiratory syncytial virus and SARS-Cov, but not adenovirus or rhinovirus. [2] A dentifrice containing 10% sodium benzoate and 0.3% dichlorobenzyl alcohol maintains antimicrobial activity for 5 to 10 minutes after ...
In these conversions, chloride is displaced. [2] Pyrithione, the conjugate base of 2-mercaptopyridine-N-oxide, is a fungicide found in some shampoos. Oxidation 2-chloropyridine gives 2-chloropyridine-N-oxide. [5] The antihistamine pheniramine may be generated via the reaction of phenylacetonitrile with 2-chloropyridine in the presence of a base ...
A typical PCC oxidation involves addition of an alcohol to a suspension of PCC in dichloromethane. [6] [7] [8] The general reaction is: 2 [C 5 H 5 NH][CrO 3 Cl] + 3 R 2 CHOH → 2 [C 5 H 5 NH]Cl + Cr 2 O 3 + 3 R 2 C=O + 3 H 2 O. For example, the triterpene lupeol was oxidized to lupenone: [9]
