Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acid derivatives with potential metabolic and cardiovascular applications. It serves as a building block in agrochemicals for the production of herbicides and plant growth regulators due to its ability to modify biological activity in targeted systems. Also employed in research laboratories for the preparation of metal-organic frameworks (MOFs) and coordination compounds, where its chelating properties enable the formation of stable complexes with transition metals. Its ethoxy and carboxylic acid functional groups allow for versatile chemical modifications, making it valuable in medicinal chemistry and materials science.
