Description

4-Bromophenyl-(4-Fluorobenzyl)Ether (CAS NO 900911-39-9) is a high-purity, specialized organic building block of significant value in advanced chemical synthesis. Its core utility lies in its bifunctional aromatic structure, featuring both bromo and fluoro substituents, which makes it a versatile intermediate for constructing complex molecules. This compound is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries for creating novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those targeting central nervous system (CNS) disorders and other therapeutic areas.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides, leveraging its halogenated aromatic core.
• Liquid Crystal & OLED Materials: Serves as a building block for creating advanced organic electronic materials due to its stable ether linkage and halogenated aromatic rings.
• Polymer Modification: Employed to introduce halogenated phenyl groups into polymer chains to alter physical properties like flame retardancy and refractive index.
• Cross-Coupling Reactions: The bromoaryl group is an excellent substrate for palladium-catalyzed reactions (e.g., Suzuki, Heck), enabling rapid diversification of molecular structures.
• Ligand & Catalyst Development: Useful for synthesizing specialized ligands for metal catalysis in asymmetric synthesis and other fine chemical processes.
