  • Applications

    Osajin (CAS 482-53-1) is a natural flavonoid typically evaluated as an intermediate in organic synthesis and as a bioactive scaffold in research. In industry, it is commonly assessed for antioxidant activity and radical-scavenging properties, with potential applications in cosmetics/personal care formulations and in food processing as a natural antioxidant; in pharmaceutical research, it may serve as a lead compound for flavonoid-based therapeutics. Additionally, its radical-stabilizing characteristics are being explored for applications in coatings and polymer formulations to enhance material stability.
