Used primarily as a chemical intermediate in organic synthesis, particularly in the production of cyanoacrylate esters which are key components in fast-acting adhesives (commonly known as "super glues"). It serves as a precursor in the Knoevenagel condensation reaction to form α,β-unsaturated nitriles, which are building blocks for pharmaceuticals, agrochemicals, and dyes. Its reactivity makes it valuable in the synthesis of fine chemicals and specialty esters. Also utilized in fragrance formulations due to its ability to contribute fruity or floral notes when modified. Handles under controlled conditions due to its reactivity and potential irritant properties.
