Used as a key intermediate in the synthesis of functional organic materials, particularly in the development of nonlinear optical materials and fluorescent dyes. Its electron-deficient structure makes it valuable in constructing conjugated systems for optoelectronic applications. It also serves as a building block in pharmaceutical research, where it participates in cycloaddition and nucleophilic addition reactions to form complex heterocyclic compounds. Additionally, it is employed in the preparation of specialty polymers with enhanced thermal and electronic properties.
