  • Applications

    Noreugenin (CAS 1013-69-0) is used primarily as an intermediate and building block in organic synthesis for pharmaceutical and fragrance-related chemistry; it is also considered a potential polyphenol building block for cosmetic and personal care formulations; it is frequently evaluated for roles in the synthesis of flavonoid derivatives in medicinal chemistry research; in coatings and inks, noreugenin can serve as a precursor to derivatives that impart color and stability; overall, it is viewed as a useful reagent in industrial research for developing complex synthetic routes and new materials.
