Application

p-Isopropenylphenol serves as a key monomer in the synthesis of high-performance phenolic resins and thermosetting polymers. It is particularly valuable in adhesive formulations where its dual functionality enables crosslinking with formaldehyde or epoxy systems. Researchers also utilize this compound as a building block for advanced materials like liquid crystal polymers and photoresists. In pharmaceutical intermediates, it acts as a precursor for antioxidants and UV stabilizers.
