Description

Oxalyl Fluoride is a highly reactive and versatile fluorinating agent and chemical intermediate. Its primary value lies in its ability to efficiently introduce fluorine atoms or oxalyl groups into target molecules, enabling the synthesis of complex fluorinated compounds. This makes it a critical reagent for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise fluorination chemistry.

Application

• Pharmaceutical Synthesis: Key intermediate in the production of active pharmaceutical ingredients (APIs), particularly for introducing fluorine atoms to enhance metabolic stability and bioavailability.
• Agrochemical Manufacturing: Used in the synthesis of advanced herbicides, pesticides, and fungicides where fluorinated compounds offer improved efficacy and environmental profile.
• Fluorinated Polymer Production: Serves as a monomer or modifying agent in the creation of specialty polymers with enhanced chemical resistance, thermal stability, and low surface energy.
• Organic Synthesis & Research: A valuable reagent for laboratory-scale fluorination reactions, cyclizations, and the preparation of heterocyclic compounds in academic and industrial R&D.
• Electrolyte Additives: Investigated for use in lithium-ion battery electrolytes to improve performance and stability at high voltages.
• Surface Modification: Employed in the chemical vapor deposition (CVD) or treatment of surfaces to create fluorinated layers with specific properties.

Quality Control

Our Oxalyl Fluoride is produced and handled under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) and NMR, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP and ISO 9001 standards for reliable supply to regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its hygroscopic and moisture-sensitive nature, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from strong bases and incompatible materials.
