  • Applications

    Dihydropinosylvin (CAS 14531-52-3) is primarily used as a synthetic intermediate and building block for stilbene derivatives, and is evaluated as an antioxidant and stabilizer for polymers and coatings. It is also investigated as a precursor for fragrance-related and cosmetic stilbene compounds. Owing to the antimicrobial and antifungal properties associated with stilbenes, potential applications include wood protection formulations and coating systems with mold resistance, as well as potential use in cleaning and household formulations subject to local regulations.
