  • Applications

    3-Pentadecylphenol (CAS 501-24-6) is used primarily as a specialty chemical intermediate with applications across several industries. In perfumery and cosmetics, it can serve as a high-molecular-weight fragrance ingredient or fixative. In polymers, coatings, and adhesives, it is evaluated as a building block for specialty additives such as antioxidants or UV-stabilizer precursors and as a source of functional aryl-alkyl components in formulations. It may also appear in cleaning and household formulations as a fragrance constituent or processing aid under formulation limits. Usage is typically subject to local regulations and formulation constraints.
