Description

Sodium 3,5-Difluorobenzoate is the sodium salt derivative of 3,5-difluorobenzoic acid, a valuable fluorinated aromatic building block. This compound is prized for its role as a key intermediate in the synthesis of complex molecules, particularly in the pharmaceutical and agrochemical sectors, where the introduction of fluorine atoms is critical for modulating biological activity and stability. It serves as an essential precursor for researchers and manufacturers developing active pharmaceutical ingredients (APIs), advanced materials, and specialty fine chemicals.

Application

• Pharmaceutical Intermediate: A crucial building block in the synthesis of active pharmaceutical ingredients (APIs), especially for drugs containing difluorophenyl motifs.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides where fluorination enhances efficacy and environmental persistence.
• Liquid Crystal & OLED Materials: Serves as a precursor in the manufacture of fluorinated organic compounds for electronic displays and optoelectronic devices.
• Polymer Modification: Employed to introduce fluorine-containing side chains into polymers, improving their chemical resistance, thermal stability, and surface properties.
• Organic Synthesis & Research: A versatile reagent in academic and industrial R&D for constructing complex fluorinated aromatic structures.
• Coordination Chemistry: Can act as a ligand or counterion in the preparation of metal-organic frameworks (MOFs) and catalysts.

Quality Control

Our Sodium 3,5-Difluorobenzoate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for research and industrial synthesis. Certificates of Analysis (COA) with detailed batch-specific results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from strong acids and strong oxidizing agents.
