Noncombustible solid, but dust may explode in cloud form. Contact with strong oxidizers may cause a fire or explosion hazard | [Description]
Clopidol is a coccidiostat.1 It prevents mortality of chickens infected with the parasites E. tenella, E. necatrix, E. acervuline, E. mivati, E. brunetti, and E. maxima. It has antimalarial activity against P. berghei in mice and P. cynomologi in rhesus macaques.2 Clopidol is a potential contaminant in food poultry.3 Formulations containing clopidol have been used in the prevention of coccidiosis in chickens. | [Description]
The drug methylchlorpindol is used for the prevention
of coccidiosis in poultry. | [Chemical Properties]
Clopidol is a white to light brown powder.
| [Waste Disposal]
Dispose of contents and container to an approved waste disposal plant. All federal, state, and local environmental regulations must be observed. It is inappropriate and possibly dangerous to the environment to dispose of expired or waste drugs and pharmaceuticals by flushing them down the toilet or discarding them to the trash. Household quantities of expired or waste pharmaceuticals may be mixed with wet cat litter or coffee grounds, double-bagged in plastic, discard in trash. Larger quantities shall carefully take into consideration applicable DEA, EPA, and FDA regulations. If possible return the pharmaceutical to the manufacturer for proper disposal being careful to properly label and securely package the material. Alternatively, the waste pharmaceutical shall be labeled, securely packaged, and transported by a state licensed medical waste contractor to dispose by burial in a licensed hazardous or toxic waste landfill or incinerator. | [Synthesis]
The general procedure for the synthesis of 3,5-dichloro-2,6-dimethylpyridin-4-ol from ethyl acetoacetate is as follows: 130 g (1 mole) of ethyl acetoacetate, 39 g of styrene-DVB (D301T) resin, and 100 ml of distilled water were added sequentially to three 500 ml three-necked flasks. The reaction mixture was reacted under stirring for 30 hours, during which 85 g (5 moles) of ammonia gas was released. Subsequently, 142 g (2 moles) of chlorine gas was passed into the reaction system and the reaction was continued with stirring for 2 hours. The reaction temperature was maintained at 30°C. Upon completion of the reaction, the styrene-DVB (D301T) resin was removed by filtration, and the solid cake of the resin was washed with 100 mL of 10% aqueous sodium hydroxide. The styrene-DVB (D301T) resin was recycled. The filtrate was distilled to remove a small amount of ethanol and then left to crystallize. The crystallized product was filtered and dried to give 87.8 g of 3,5-dichloro-2,6-dimethylpyridin-4-ol in 91.5% yield. | [storage]
