  • Applications

    9-Formylnonanoic acid (CAS number: 5578-80-3) is commonly evaluated as an intermediate in fragrance chemistry and aroma ingredient synthesis. It may be used as a building block for long-chain esters and related derivatives for cosmetics and personal care. It serves as a precursor for specialty polymers and plasticizers and can be incorporated into coatings and inks formulations as a chemical intermediate. It is used as a starting material for surfactant synthesis in cleaning products, and acts as a versatile intermediate in broader industrial chemical manufacturing, all subject to local regulations and formulation limits.
