  • Applications

    Rlm 45 (CAS 27306-90-7) is a material considered for multiple applications in fragrance and chemical industries. In perfumery, it is evaluated as an odorant component or a fixative used in perfume formulations and personal care products. It may also be used as a flavor ingredient in food and beverage applications. In cosmetics/personal care, it can contribute to fragrance profiles and overall scent stability. In household products and cleaning formulations, it may be added as a fragrance ingredient. Additionally, it may be used as an intermediate in chemical synthesis depending on process requirements and regulatory considerations.
