  • Applications

    Maclurin (CAS 519-34-6) is a natural polyphenolic compound that may serve as an intermediate or building block in organic synthesis, with potential applications in cosmetics and coatings. It is often evaluated as an antioxidant additive in personal care formulations and as a pigment/dye precursor for colorants used in coatings and inks. Additionally, its phenolic structure supports use as a stabilizer or chelating component in polymer formulations and it is sometimes explored for UV-screening or polymer-protective roles, subject to local regulations and formulation limits.
