Description

4-Bromo-3-Fluoro-2-Methoxy-Benzaldehyde is a high-purity, multi-functional aromatic aldehyde building block designed for advanced organic synthesis. This compound is valued for its precise molecular architecture, which enables the introduction of bromo, fluoro, and methoxy substituents in a single, strategically positioned scaffold. It is an essential intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries seeking to develop novel active ingredients and functional molecules.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for molecules targeting central nervous system (CNS) disorders, oncology, and anti-inflammatory applications.
• Agrochemical Synthesis: Used in the development of next-generation herbicides, fungicides, and insecticides, where the halogen and methoxy groups contribute to bioactivity and environmental stability.
• Liquid Crystal & OLED Materials: Serves as a building block for advanced electronic materials, including liquid crystal displays (LCDs) and organic light-emitting diodes (OLEDs), due to its aromatic core and functional handles.
• Cross-Coupling Reactions: The bromo substituent makes it an excellent substrate for palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck, Sonogashira) to construct complex biaryl systems.
• Fluorinated Compound Research: An important reagent for studying the effects of fluorine introduction on the pharmacokinetics and metabolic stability of candidate drug molecules.
• Custom Synthesis & Contract Manufacturing: Supplied to CROs and CDMOs for custom synthesis projects requiring high-fidelity, functionalized benzaldehyde derivatives.
