Product Benefits

Tetrachloropyridine products are mainly used as pharmaceutical intermediates and pesticide intermediates. In the pesticide industry, tetrachloropyridine is a key raw material for the synthesis of the insecticide chlorpyrifos and the herbicide picloram. Compared with traditional methods, the process for synthesizing chlorpyrifos using tetrachloropyridine as a raw material can significantly reduce production costs and wastewater discharge, and has already achieved conversion in ten-thousand-ton-scale facilities in industrial production. In addition, tetrachloropyridine can also be used to synthesize pentachloropyridine in one step via chlorination, and the latter is a key intermediate for herbicides such as fluroxypyr.
