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 ...
Dichloropyridines are organic compounds with the formula Cl 2 C 5 H 3 N, consisting of a pyridine ring substituted with two chlorides. [1] Six isomers are known. They are white or colorless, most are solids at room temperature.
The initially formed 2-chloropyridine reacts further to give 2,6-dichloropyridine. [2] Alternatively, 2-chloropyridines can be conveniently synthesized in high yields from pyridine-N-oxides. [3] 2-Chloropyridine was originally prepared by the chlorination of 2-hydroxypyridine with phosphoryl chloride. [4]
Direct halogenation of pyridine with chlorine gas above 270 °C gives a mixture of 2-chloropyridine and 2,6-dichloropyridine. [1] 2- and 4-chloropyridine are prepared from the corresponding pyridinols using phosphoryl chloride. [1]
Dipicolinic acid (pyridine-2,6-dicarboxylic acid or PDC and DPA) is a chemical compound which plays a role in the heat resistance of bacterial endospores. It is also used to prepare dipicolinato ligated lanthanide and transition metal complexes for ion chromatography .

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.
From January 2008 to December 2012, if you bought shares in companies when Orrin H. Ingram II joined the board, and sold them when he left, you would have a -6.7 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
