Used primarily as an intermediate in the synthesis of agricultural chemicals, particularly in the production of insecticides and herbicides. It plays a key role in the manufacture of chlorpyrifos and related organophosphate compounds, which are widely applied in crop protection for controlling a broad spectrum of pests in agriculture and horticulture. Due to its reactivity, it enables the introduction of pyridine-based structures into active ingredients, enhancing their efficacy and selectivity. Its use is mostly confined to industrial settings where strict safety and environmental controls are in place.
