Description

5-Benzofurancarboxaldehyde,2-Fluoro-(9Ci) is a high-purity fluorinated benzofuran derivative, serving as a critical advanced intermediate in modern synthetic chemistry. Its value lies in the strategic incorporation of fluorine and an aldehyde functional group onto the benzofuran scaffold, enabling precise molecular modifications for performance enhancement. This compound is primarily needed by research and development teams in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of fluorinated drug candidates, particularly in oncology, CNS, and anti-inflammatory research.
• Agrochemical Synthesis: Used in developing next-generation herbicides, fungicides, and insecticides where the benzofuran core and fluorine atom improve efficacy and environmental profile.
• Material Science Research: Serves as a precursor for organic electronic materials, such as OLED (Organic Light-Emitting Diode) emitters and charge-transport molecules.
• Fluorine Chemistry Studies: An essential reagent for investigating structure-activity relationships (SAR) and the effects of fluorination on biological activity and material properties.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for client-specific custom synthesis projects.
