  • Applications

    Koraiol, CAS 72188-51-3, is primarily regarded as an aroma compound with potential real-world applications in the fragrance and cosmetics sectors; it is commonly evaluated as a scent ingredient for perfumes and personal care products. It may also function as an intermediate in the synthesis of other fragrance materials used in industrial aroma chemistry. Additionally, koraiol could be considered for inclusion in household cleaning products and air-freshening formulations to contribute odor characteristics, subject to formulation limits and regulatory requirements. In broader materials applications, it may be explored as a fragrance-related additive in polymers or coatings manufacturing, depending on compatibility and regulatory constraints.
