Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs and other biologically active compounds. It plays a key role in the development of agrochemicals, including herbicides and insecticides, due to its ability to enhance the efficacy of active ingredients. Also utilized in the creation of dyes and functional materials where nitrogen-containing heterocycles are required. Its reactivity makes it valuable in organic synthesis for building complex pyridine-based structures.
