Description

Perfluorononanoic Acid CAS NO 375-95-1 is a high-purity, fully fluorinated carboxylic acid characterized by its exceptional chemical and thermal stability. This compound serves as a critical intermediate and functional additive in advanced material science and specialty chemical synthesis. It is essential for manufacturers and R&D facilities in the fluoropolymer, surface treatment, and electronics industries seeking to enhance product performance through fluorination.

Application

• Fluoropolymer Production: Acts as a key surfactant and processing aid in the emulsion polymerization of PTFE (polytetrafluoroethylene) and other high-performance fluoropolymers.
• Surface Treatment & Coatings: Used to impart oil, water, and stain repellency to textiles, carpets, paper, and leather products.
• Specialty Chemical Synthesis: Serves as a versatile building block for synthesizing fluorinated surfactants, pharmaceuticals, and agrochemical intermediates.
• Fire-Fighting Foams (Historical/Formulative): A component in the formulation of aqueous film-forming foams (AFFF) for liquid fuel fires.
• Electronics Industry: Employed in the etching and cleaning processes for semiconductor manufacturing and as a precursor for dielectric fluids.
• Analytical Chemistry: Utilized as a standard or reference material in environmental and analytical testing for per- and polyfluoroalkyl substances (PFAS).

Quality Control

Our Perfluorononanoic Acid is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong bases, oxidizers, and sources of ignition. Due to its nature as a perfluoroalkyl substance, appropriate environmental containment measures should be observed.
