Used primarily as a key intermediate in the synthesis of agrochemicals, including chloropyridine-based insecticides such as neonicotinoids and certain herbicides for crop protection. Its structure facilitates modifications like esterification or etherification to produce compounds with targeted biological activity against pests and weeds. The pyridine backbone also makes it suitable for developing plant growth regulators that interact with natural signaling pathways. Furthermore, it acts as a versatile building block in the preparation of pharmaceuticals requiring chlorinated pyridine moieties for enhanced bioactivity.
