Description

Sodium 4-Chloro-2,5-Difluorobenzoate CAS NO 1421029-91-5 is a high-purity, organofluorine building block salt essential for advanced synthetic chemistry. Its value lies in providing a stable, soluble sodium carboxylate form of the corresponding benzoic acid, facilitating precise reactions in controlled environments. This compound is primarily needed by research and development laboratories and production facilities in the pharmaceutical and agrochemical sectors for constructing complex molecules.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing difluorophenyl motifs for enhanced metabolic stability and bioavailability.
• Agrochemical Synthesis: Used in the production of advanced herbicides and pesticides, where the chloro-difluoro substitution pattern contributes to specific biological activity.
• Liquid Crystal & OLED Material Precursor: Serves as a starting material for synthesizing fluorinated aromatic compounds used in electronic display technologies.
• Organic Synthesis Reagent: Employed in cross-coupling reactions (e.g., Suzuki, Negishi) and nucleophilic aromatic substitution reactions as a versatile electrophile or anionic nucleophile.
• Fluorinated Polymer Modification: Acts as a monomer or modifier in the development of specialty polymers with unique chemical resistance and surface properties.
• Chemical Research & Development: Utilized in academic and industrial R&D for exploring new synthetic methodologies and creating novel fluorinated compounds.

Quality Control

Our Sodium 4-Chloro-2,5-Difluorobenzoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation (NMR, IR), to ensure it meets stringent specifications for research and production use. Certificates of Analysis (COA) detailing batch-specific results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. Keep away from incompatible materials.
