Used primarily as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block in the manufacture of trimethylacetic acid and related derivatives. Commonly employed in condensation reactions due to its reactive aldehyde group, it contributes to the formation of resins, plasticizers, and specialty solvents. Also utilized in the fragrance industry for synthesizing aroma compounds owing to its ability to form esters with pleasant odors. Its volatility and reactivity make it suitable for use in controlled reaction environments where selective aldehyde transformations are required.
