Description

tert-Butyl 20-Bromoicosanoate is a high-purity, long-chain fatty acid derivative featuring a terminal bromine atom, making it a versatile intermediate for advanced organic synthesis. This compound is particularly valued for its role in the controlled introduction of the icosanoate moiety and for facilitating further functionalization via the bromine handle. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise building blocks for lipid conjugation, polymer modification, and the development of bioactive molecules.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of lipid-drug conjugates, prodrugs, and bioactive molecules targeting metabolic pathways.
• Agrochemical Synthesis: Used in the development of novel surfactants, emulsifiers, and active ingredients with tailored lipophilic properties.
• Polymer Science: Serves as a monomer or modifier for creating specialty polymers with specific chain lengths and functional end-groups.
• Lipid Research: Essential tool in biochemical research for studying membrane dynamics, lipid metabolism, and as a precursor for labeled fatty acids.
• Material Science: Intermediate for surface modification agents, lubricant additives, and advanced organic coatings.
• Cross-Coupling Reactions: The terminal bromine atom makes it a suitable substrate for palladium-catalyzed reactions like Suzuki or Heck couplings to create complex organic architectures.
