Description

3,7,11-Trimethyl-1-Dodecanol is a branched-chain fatty alcohol, also known as a synthetic farnesol isomer. This compound serves as a versatile intermediate and building block in the synthesis of complex organic molecules, prized for its specific carbon skeleton and terminal hydroxyl functionality. It is particularly valuable for manufacturers in the fragrance, flavor, and specialty chemical industries seeking to create or modify organoleptic profiles and advanced materials.

Application

• Fragrance and Flavor Ingredient: Used as a key intermediate in the synthesis of sophisticated musk, floral, and woody aroma chemicals.
• Pharmaceutical Intermediates: Serves as a chiral building block in the research and development of active pharmaceutical ingredients (APIs).
• Specialty Surfactants and Esters: Acts as a precursor for producing high-performance, branched nonionic surfactants and plasticizer esters.
• Lubricant Additives: Utilized in the formulation of synthetic lubricants and functional fluids requiring specific thermal and oxidative stability.
• Agrochemical Synthesis: Employed as an intermediate in the production of certain pesticides and plant growth regulators.
• Research & Development: A valuable standard and starting material in organic chemistry research for terpene and sesquiterpene analog synthesis.
