Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals. It plays a key role in the production of certain herbicides and insecticides due to its reactivity in forming carbon-carbon bonds. Also employed in the manufacture of dyes and pigments, where it contributes to chromophore development. Its ester and carbonyl functional groups make it valuable in organic synthesis, particularly in condensation reactions like the Claisen and Knoevenagel reactions. Additionally, it serves as a building block for heterocyclic compounds such as pyrazoles and pyrimidines, which are common structures in active pharmaceutical ingredients.
