Description

Eicosanoic Acid, 20-Bromo- is a high-purity, synthetically modified fatty acid derivative, distinguished by the strategic bromination at the terminal carbon of the eicosanoic acid chain. This specific halogenation makes it a valuable and versatile building block for advanced organic synthesis and materials science research. It is particularly sought after by R&D chemists and process developers in the pharmaceutical, agrochemical, and specialty polymer industries for creating novel compounds with tailored properties.

Application

• Pharmaceutical Intermediate: Serves as a key synthon for the development of new active pharmaceutical ingredients (APIs), especially in lipid-based drug discovery and prodrug synthesis.
• Agrochemical Research: Used in the synthesis of novel surfactants, adjuvants, and bioactive molecules for crop protection formulations.
• Polymer & Material Science: Acts as a functional monomer or chain-transfer agent for modifying polymer backbones, introducing bromine handles for further cross-linking or grafting reactions.
• Organic Synthesis Building Block: The terminal bromine atom provides an excellent site for nucleophilic substitution (e.g., SN2 reactions) or metal-catalyzed cross-coupling reactions (e.g., Suzuki, Heck).
• Liquid Crystal & Advanced Material Precursor: Utilized in the research and development of specialty chemicals for electronic displays and functional coatings.
• Biochemical Probe Synthesis: Employed to create labeled fatty acid analogs for metabolic pathway studies and biochemical assays.
