Description

6,7-Dichlorononafluoro-5-Oxaheptanoic Acid is a highly fluorinated, chlorinated carboxylic acid derivative, serving as a critical building block for advanced fluorochemical synthesis. Its unique perfluoroalkyl ether chain terminated with a reactive acid group makes it a valuable precursor for creating surfactants, polymers, and specialty materials with exceptional chemical and thermal stability. This compound is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and high-performance materials industries for developing novel fluorinated compounds.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) requiring fluorinated motifs to enhance metabolic stability and bioavailability.
• Agrochemical Synthesis: Serves as a key precursor for creating advanced herbicides and pesticides with improved environmental persistence and efficacy.
• Fluorinated Surfactant Production: Acts as a raw material for manufacturing high-performance surfactants and emulsifiers used in demanding industrial applications.
• Polymer Modification: Employed to introduce fluorinated segments into polymers, imparting oil, water, and chemical resistance to coatings and elastomers.
• Specialty Material Research: Utilized in R&D for developing novel materials with specific surface properties for electronics and aerospace.
• Chemical Synthesis Reagent: Functions as a versatile reagent in organic synthesis for constructing complex molecules containing perfluoroalkyl ether groups.

Quality Control

Our production of 6,7-Dichlorononafluoro-5-Oxaheptanoic Acid adheres to stringent internal quality standards to ensure batch-to-batch consistency and purity. Each lot is analyzed using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment, supporting 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 constructed of compatible materials (e.g., PTFE, fluorinated polymers). Recommended storage temperature: 2-25°C.
