Description

2,2,3,3,4,4,5,5,6,6,7,7-Dodecafluoroheptanoic Acid, Sodium Salt is a highly fluorinated organic salt valued for its unique combination of hydrophobicity and oleophobicity imparted by the perfluorinated alkyl chain. This compound serves as a critical intermediate and functional additive in advanced material science and specialty chemical synthesis. It is primarily sought by manufacturers in the polymer, surfactant, and pharmaceutical industries for developing products with enhanced surface properties, chemical resistance, and stability.

Application

• Fluorinated Surfactant and Emulsifier: Key component in fire-fighting foams, coatings, and specialty cleaning formulations where extreme wetting and leveling are required.
• Polymer Modification: Used as a comonomer or additive to impart oil, water, and stain resistance to fluoropolymers and high-performance plastics.
• Pharmaceutical Intermediate: Serves as a building block for synthesizing fluorinated active pharmaceutical ingredients (APIs) and prodrugs.
• Lithium-Ion Battery Electrolytes: Functions as an electrolyte additive to improve thermal stability and cycle life of batteries.
• Textile and Leather Treatment: Imparts durable water and oil repellency (DWR) finishes to fabrics and leather goods.
• Electronic Chemicals: Used in the formulation of anti-reflective coatings and etching agents for semiconductor manufacturing.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry, and well-ventilated area. Recommended storage temperature is between 15°C and 25°C. Keep the container tightly sealed when not in use to prevent absorption of moisture from the atmosphere.
