Description

Oxyfluorocarboxylic Acid CAS NO 626138-21-4 is a specialized fluorinated organic acid characterized by the presence of both fluorine atoms and a carboxylic acid functional group. This unique molecular architecture imparts distinct chemical properties, making it a valuable intermediate for synthesizing advanced materials and fine chemicals. It is primarily sought after by research and development teams and production chemists in the pharmaceutical, agrochemical, and advanced polymer industries.

Application

• Pharmaceutical Intermediate: A key building block for the synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring enhanced metabolic stability or lipophilicity.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and pesticides, where the fluorine moiety can improve biological activity and environmental persistence.
• Fluorinated Polymer Production: Serves as a monomer or modifier in the creation of specialty polymers with superior chemical resistance, thermal stability, and low surface energy.
• Liquid Crystal & Electronic Materials: Employed in the development of fluorinated components for liquid crystal displays (LCDs) and dielectric materials in the electronics sector.
• Catalyst & Ligand Preparation: Acts as a precursor for synthesizing fluorinated ligands used in asymmetric catalysis and other advanced synthetic methodologies.
• Surface Modification Agent: Utilized to introduce fluorine-containing groups onto material surfaces to alter wettability and adhesion properties.

Quality Control

Our Oxyfluorocarboxylic Acid is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets precise customer specifications and industry benchmarks. Certificates of Analysis (COA) documenting 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, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Due to its nature as a strong acid/organic solvent, containers must be kept tightly sealed and handled with appropriate chemical hygiene practices. Recommended long-term storage temperature is 2-8°C.
