Used in the development of agrochemicals, particularly in the synthesis of pesticides and herbicides, where it acts as a key intermediate. Its structure allows for the creation of compounds that target specific pests or weeds effectively.

Applied in pharmaceutical research for the design of novel drug molecules, especially in the development of inhibitors or modulators for biological targets. The deuterium (D5) labeling in the ethyl group can be useful in metabolic studies and tracing the behavior of the compound in biological systems.

In material science, it serves as a building block for the synthesis of advanced materials, such as liquid crystals or organic semiconductors, due to its pyridine core and functional groups that enable further chemical modifications.

Also utilized in organic synthesis as a versatile intermediate for constructing complex molecules, particularly in the preparation of heterocyclic compounds, which are valuable in various industrial and research applications.
