  • Applications

    Chemical name: 1-((2R,3R)-3,4-Dihydro-3,5,7-trihydroxy-2H-1-benzopyran-2-yl)-8-((2R,3S)-3,4-dihydro-3,5,7-trihydroxy-2H-1-benzopyran-2-yl)-3,4,6-trihydroxy-5H-benzocyclohepten-5-one; CAS number: 31701-93-6. The compound is a highly polyhydroxylated, multi-ring polyphenolic structure and is typically encountered as a synthetic intermediate and building block in medicinal chemistry and pharmaceutical research. Its dense phenolic hydroxyl motifs may confer antioxidant and metal-chelating properties, making it a candidate for exploration in cosmetic/personal care formulations as an antioxidant/stabilizer, subject to formulation limits. In polymer and coating applications, such polyphenolic frameworks are investigated as radical scavengers and stabilizers to improve aging resistance and compatibility with resins. It may also serve as an analytical reference standard or research reagent in analytical chemistry for polyphenol characterization and method development. Additionally, the use of this compound in other domains is highly dependent on local regulations and specific formulation constraints.
