Description

4-Nonanol is a versatile nine-carbon aliphatic alcohol, also known as nonyl alcohol, with the CAS registry number 5932-79-6. This compound serves as a valuable intermediate and functional ingredient across several high-value industrial sectors due to its hydrophobic alkyl chain and reactive hydroxyl group. It is particularly essential for manufacturers in the fragrance, plasticizer, and specialty chemical industries seeking reliable building blocks for synthesis.

Application

• Fragrance and Flavor Intermediate: Used in the synthesis of esters and other derivatives that contribute fruity, floral, or waxy notes to perfumes, cosmetics, and food flavorings.
• Plasticizer Production: Acts as a precursor for phthalate and other ester-based plasticizers, which are used to increase the flexibility and durability of polymers like PVC.
• Surfactant and Detergent Synthesis: Serves as a hydrophobic feedstock for producing nonionic surfactants, emulsifiers, and cleaning agents.
• Lubricant Additive: Employed in the formulation of synthetic lubricants and metalworking fluids where its structure contributes to desired viscosity and stability properties.
• Chemical Solvent: Functions as a medium-polarity solvent in various organic synthesis and extraction processes.
• Pharmaceutical Intermediates: Utilized in the controlled synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
