Description

7-Chloroperfluoroheptanoic Acid is a highly fluorinated carboxylic acid derivative, distinguished by its unique perfluoroalkyl chain terminated with a reactive acid chloride group. This structure makes it a valuable intermediate for introducing perfluorinated segments with a functional handle, offering exceptional chemical and thermal stability alongside hydrophobic and oleophobic properties. It is primarily sought by manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for synthesizing specialty surfactants, polymers, and surface-modifying agents.

Application

• Fluorinated Surfactant & Polymer Intermediate: A key building block for synthesizing high-performance fluorosurfactants and fluoropolymers used in coatings, fire-fighting foams, and electronics.
• Pharmaceutical & Agrochemical Synthesis: Serves as a versatile intermediate for creating novel active ingredients with enhanced metabolic stability and bioavailability.
• Surface Modification & Textile Treatment: Used to impart durable water, oil, and stain repellency to textiles, leather, and non-woven fabrics.
• Specialty Additives: Employed in the formulation of advanced lubricants, greases, and corrosion inhibitors for extreme environments.
• Lithography & Semiconductor Processing: Acts as a precursor for photoresists and other chemicals used in microelectronics fabrication.
• Analytical Chemistry & Research: Utilized as a standard or reagent in chemical research and development of fluorinated compounds.

Quality Control

Our 7-Chloroperfluoroheptanoic Acid is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including GC, NMR, and titration methods, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, assay, and impurity profiles is provided with every shipment to guarantee compliance with your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place away from incompatible materials such as strong bases, oxidizers, and moisture. Due to its nature as a strong acid/organic solvent, appropriate secondary containment is recommended. For long-term storage, maintain at temperatures between 2°C and 8°C under an inert atmosphere to preserve stability.
