Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acid derivatives with biological activity. It serves as a building block in the preparation of pyridine-based compounds, which are important in medicinal chemistry for their role in enzyme inhibition and receptor modulation. Commonly employed in the creation of antihypertensive agents and other cardiovascular drugs due to its ability to mimic structural motifs in bioactive molecules. Also utilized in agrochemical research for designing new pesticides and plant growth regulators. Its aldehyde and ester functional groups allow for diverse chemical modifications, making it valuable in combinatorial chemistry and drug discovery.
