  • Applications

    (2S)-2-((2R,3R)-2,3-Dihydro-2-(4-hydroxy-3-methoxyphenyl)-3-(hydroxymethyl)-1,4-benzodioxin-6-yl)-2,3-dihydro-5,7-dihydroxy-4H-1-benzopyran-4-one (CAS 70815-32-6) is typically explored as a synthetic building block and intermediate in pharmaceutical and fine-chemical manufacturing. In cosmetics and personal care, it may be evaluated as an antioxidant ingredient or as a precursor for polyphenol-derived colorants. In fragrance and flavor applications, it could be used as a fragrance component or aroma precursor after safety and regulatory assessment. In coatings, inks, and polymer formulations, it may serve as an antioxidant stabilizer or UV-stabilizing additive, helping to mitigate polymer degradation. It also may find utility as a chemical intermediate in agrochemical or specialty chemical syntheses, subject to regulatory compliance.
