  • Applications

    Pinosylvin (CAS 22139-77-1) is primarily used as a natural antifungal and antioxidant in wood protection formulations, helping deter fungal decay in treated timber. It is also evaluated as a bio-based antioxidant and active ingredient for cosmetics and personal care products, contributing to oxidative stability. In industrial coatings and inks, it can serve as a stilbene-derived additive or intermediate for UV-stable formulations, and it is explored as a renewable building block for specialty polymers. Additionally, it is studied as a starting point for synthesizing stilbene derivatives in chemical research. Use in any application remains subject to local regulations and formulation limits.
