Description

4,4,5,5,6,6,7,7,8,8,9,9,10,11,11,11-Hexadecafluoro-2-Hydroxy-10-(Trifluoromethyl)Undecyl Dihydrogen Phosphate is a highly fluorinated phosphate ester surfactant, valued for its exceptional surface activity and stability in aggressive chemical environments. This compound is engineered to deliver superior performance where conventional surfactants fail, particularly in systems involving strong acids and organic solvents. It is a critical material for advanced industrial applications in electronics manufacturing, specialty coatings, and high-performance lubricant formulations.

Application

• Electronics Manufacturing: As a key wetting and leveling agent in acidic plating baths and photoresist strippers for semiconductor and printed circuit board (PCB) fabrication.
• Fluorinated Surfactant & Additive: Used in the formulation of fire-fighting foams, stain-resistant coatings, and as a processing aid for fluoropolymers.
• Specialty Coatings & Inks: Provides improved substrate wetting, flow, and leveling in solvent-based coating systems, especially for demanding industrial applications.
• High-Performance Lubricants: Acts as an extreme-pressure additive and corrosion inhibitor in synthetic lubricants for harsh operating conditions.
• Chemical Synthesis Intermediate: Serves as a building block for synthesizing more complex fluorinated phosphate derivatives and specialty chemicals.
• Oil & Gas Industry: Potential use as a surfactant in acidizing fluids and other well stimulation treatments.

Quality Control

Our production of 4,4,5,5,6,6,7,7,8,8,9,9,10,11,11,11-Hexadecafluoro-2-Hydroxy-10-(Trifluoromethyl)Undecyl Dihydrogen Phosphate adheres to a strict quality management system. Every batch undergoes rigorous analytical testing, including assay by titration, impurity profiling, and confirmation of identity, to ensure consistency and compliance with customer specifications. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its chemical nature as a strong acid/organic solvent-compatible material, keep away from incompatible substances such as strong bases and oxidizing agents. The container must be kept tightly sealed to prevent moisture absorption.
