Caso 1: Síntese farmacêutica
A pharmaceutical company was developing a new anti - cancer drug. 5 - chloro-2,3 - difluoropyridine was used as an intermediate in the synthesis process. Through a multi - step reaction, it was successfully incorporated into the drug molecule. The new drug showed excellent anti - cancer activity in pre - clinical trials. It could specifically target cancer cells and inhibit their growth and proliferation, while having less toxicity to normal cells.
Case 2: Agrochemical Preparation
An agrochemical research institution used 5 - chloro-2,3 - difluoropyridine to synthesize a new type of insecticide. After field trials, this insecticide demonstrated high efficiency in controlling a variety of pests on wheat crops. It could quickly kill pests and had a long - lasting effect, significantly reducing the damage of pests to wheat and increasing the wheat yield by about 20%.
