Description

3-(3-Bromo-4-Fluoro-Phenyl)-Propionaldehyde is a high-purity fluorinated and brominated aromatic aldehyde building block, essential for advanced organic synthesis. This compound matters as a versatile intermediate that enables the precise introduction of both bromine and fluorine substituents into complex molecular architectures, facilitating the development of novel materials and active compounds. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries for creating new active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly in drug discovery programs targeting CNS disorders and oncology.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides, where the fluorine atom enhances biological activity and metabolic stability.
• Liquid Crystal & OLED Material Precursor: Serves as a critical starting material for synthesizing fluorinated aromatic cores used in electronic display technologies and organic light-emitting diodes (OLEDs).
• Cross-Coupling Reactions: The bromine substituent makes it an excellent substrate for palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, Sonogashira) to form complex biaryl structures.
• Fine Chemical & Specialty Polymer Intermediate: Employed in the production of specialty polymers, dyes, and advanced materials requiring specific halogenated aromatic units.
