Used primarily as an intermediate in organic synthesis, especially in the production of pharmaceuticals and agrochemicals. Its keto and carboxylic acid functional groups make it suitable for condensation reactions and cyclization processes, enabling the construction of complex ring systems found in bioactive molecules. It is also employed in the synthesis of flavor and fragrance compounds due to its ability to form esters with pleasant odors. Additionally, it serves as a building block in the development of specialty polymers and functional materials where controlled branching and polarity are required.
