Description

5,6,7,8,8-Pentamethylnonan-4-Ol CAS NO 97752-25-5 is a branched-chain tertiary alcohol with a unique, highly substituted hydrocarbon skeleton. This structural complexity makes it a valuable intermediate for synthesizing specialized fragrance and flavor compounds, as well as high-performance lubricant additives. It is primarily sought by R&D chemists and process engineers in the fine chemical, fragrance, and specialty materials industries for its ability to impart specific steric and olfactory properties.

Application

• Fragrance & Flavor Intermediate: Serves as a key building block for synthesizing novel musk analogs and woody-amber odorants due to its stable, bulky structure.
• Lubricant & Fuel Additive Synthesis: Used to produce antioxidants and viscosity index improvers, where its branched alkyl groups enhance thermal stability and solubility in hydrocarbon bases.
• Organic Synthesis Reagent: Acts as a sterically hindered alcohol in esterification and etherification reactions, useful for protecting groups or creating specialty polymers.
• Pharmaceutical Intermediates: Potential precursor in the research and development of lipophilic drug molecules requiring specific metabolic stability.
• Surfactant & Emulsifier Research: Investigated for creating non-ionic surfactants with unique branching for low-foam or high-biodegradability applications.
