Description

Sodium 3-Chloro-2,4-Difluorobenzoate CAS NO 1396762-34-7 is a high-purity, organofluorine building block essential for advanced chemical synthesis. This compound is valued for its role as a key intermediate in the development of active pharmaceutical ingredients (APIs) and agrochemicals, where its specific halogen and fluorine substitution pattern enables precise molecular modifications. It is primarily required by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce the 3-chloro-2,4-difluorobenzoate moiety into complex target molecules.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of novel drug candidates, particularly in medicinal chemistry programs targeting central nervous system (CNS) and anti-infective agents.
• Agrochemical Synthesis: Used in the production of advanced herbicides and fungicides, where the difluoro and chloro substituents contribute to biological activity and environmental stability.
• Liquid Crystal Materials: Serves as a precursor in the manufacture of fluorinated liquid crystals for display technologies.
• Polymer Modification: Employed to introduce fluorine-containing benzoate groups into polymers to enhance thermal stability, chemical resistance, and surface properties.
• Organic Synthesis Reagent: Acts as a versatile electrophile in cross-coupling reactions (e.g., Suzuki, Buchwald-Hartwig) for constructing complex aromatic systems in research and development.
• Material Science Research: Utilized in developing novel organic electronic materials and metal-organic frameworks (MOFs) due to its specific halogenated aromatic structure.

Quality Control

Our Sodium 3-Chloro-2,4-Difluorobenzoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available for every shipment upon request, providing full traceability and quality assurance for your critical processes.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect purity and handling properties.
