Description

Benzoyl Fluoride, 2,4-Difluoro- (9Ci) is a specialized fluorinated aromatic building block of significant interest in advanced organic synthesis. This compound matters for its role as a key precursor in the development of pharmaceuticals, agrochemicals, and functional materials, where its fluorine atoms and reactive carbonyl group enable precise molecular modifications. It is primarily needed by R&D chemists and process development teams in the pharmaceutical, agrochemical, and specialty chemical industries for constructing complex, fluorine-containing target molecules.

Application

• Pharmaceutical Intermediate: A critical building block for synthesizing active pharmaceutical ingredients (APIs), particularly those requiring difluorobenzoyl motifs for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides, where the fluorine atoms contribute to product efficacy and environmental persistence.
• Liquid Crystal & OLED Material Precursor: Serves as a starting material for synthesizing fluorinated aromatic cores used in electronic display technologies and organic light-emitting diodes.
• Polymer Modification: Employed to introduce fluorine-containing side chains into polymers, altering their surface properties, chemical resistance, and thermal stability.
• Cross-Coupling Reactions: Acts as an electrophilic coupling partner in palladium-catalyzed reactions (e.g., Suzuki, Stille) for creating complex biaryl structures.
• Fluorination Reagent Synthesis: Utilized as a precursor for generating other, more specialized fluorinating agents used in laboratory and industrial settings.

Quality Control

Our Benzoyl Fluoride, 2,4-Difluoro- (9Ci) is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography (HPLC, GC) and spectroscopy (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting compliance in cGMP and ISO 9001 environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its nature as a strong acid/organic solvent and high volatility, ensure containers are sealed and stored upright away from heat, sparks, and incompatible materials such as strong bases and oxidizing agents.
