Description

4-Ethyl-3-Octanol is a branched-chain aliphatic alcohol with the CAS registry number 19781-26-1. This specialty chemical intermediate is valued for its unique structure, which imparts specific steric and chemical properties useful in advanced synthesis. It is primarily sought by manufacturers in the fragrance, flavor, and pharmaceutical sectors for the production of esters and other derivatives. Its controlled synthesis ensures high purity and consistency for demanding industrial applications.

Application

• Fragrance and Flavor Intermediate: A key building block for synthesizing esters used in creating unique, long-lasting aromatic notes for perfumes and flavoring agents.
• Pharmaceutical Synthesis: Serves as a chiral intermediate or a structural component in the development of active pharmaceutical ingredients (APIs) and fine chemicals.
• Lubricant and Plasticizer Additive: Used in the production of specialized esters that function as synthetic lubricants, base oils, or plasticizers with low volatility.
• Solvent and Extraction Agent: Employed as a high-boiling point solvent in specialty coatings, inks, and extraction processes for sensitive compounds.
• Chemical Research & Development: Utilized in organic synthesis and catalysis research as a reagent or ligand precursor due to its defined stereochemistry.
• Surfactant and Emulsifier Production: Acts as a hydrophobic feedstock for manufacturing non-ionic surfactants with specific branching for enhanced performance.
