Description

Benzoyl Fluoride, 3-(Fluorosulfonyl)- (9Ci) is a specialized organofluorine building block characterized by the presence of both a benzoyl fluoride and a fluorosulfonyl functional group. This unique bifunctional structure makes it a valuable intermediate for synthesizing advanced materials and fine chemicals, particularly where the introduction of fluorine or sulfonyl fluoride moieties is required. It is primarily utilized by research and development chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key synthon for the development of novel active pharmaceutical ingredients (APIs), especially sulfonamide-based drugs and fluorine-containing bioactive molecules.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides where the fluorosulfonyl group enhances biological activity and stability.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for creating specialty polymers, such as sulfonated fluoropolymers with unique ion-exchange or membrane properties.
• Chemical Research & Development: A versatile reagent in organic synthesis for introducing the -SO2F group, enabling subsequent transformations into sulfonamides, sulfonic acids, and sulfonate esters.
• Ligand & Catalyst Design: Employed in the synthesis of complex ligands and organocatalysts for asymmetric synthesis and metal-organic frameworks (MOFs).
• Surface Modification: Used to functionalize surfaces and nanoparticles via the reactive fluorosulfonyl group, imparting specific chemical properties for sensors or coatings.

Quality Control

Our production of Benzoyl Fluoride, 3-(Fluorosulfonyl)- adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (HPLC/GC) and spectroscopy (NMR, IR), to ensure high purity and batch-to-batch consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting identity, assay, and impurity profiles. We operate under a cGMP-compliant mindset suitable for advanced intermediate applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from strong bases and oxidizing agents.
