5-Chloro-2,3-difluoropyridine CAS 89402-43-7Isicelo

I-2,3-difluoro-5-chloropyridine yinto ebalulekileyo ephakathi kwi-synthesis ye-pesticide ephezulu ye-acetochlor. Kwiminyaka elishumi yakutshanje, izibulali-zinambuzane ezinefluorinated ziye zakhula ngokukhawuleza, yaye ziye zaba yeyona nto iphambili kuphuhliso lweshishini lehlabathi lehlabathi. Phakathi kwazo, i-fluorinated pyrethroids kunye ne-fluorinated benzoylurea pesticides ziphuhlisiwe kwaye zisetyenziswe.
