Description

1,1,2,3,3,3-Hexafluoro-2-(Trifluoromethyl)Propanesulphonic Acid CAS NO 93762-09-5 is a highly fluorinated sulfonic acid derivative, characterized by its exceptional acidity and thermal stability. This compound is a critical advanced intermediate for synthesizing high-performance materials and specialty chemicals where standard acids are insufficient. It is primarily sought by R&D and production teams in the pharmaceutical, agrochemical, and advanced polymer industries for developing novel compounds with enhanced properties.

Application

• Catalyst and Reagent in Organic Synthesis: Employed as a superacidic catalyst for demanding reactions like Friedel-Crafts alkylation, acylation, and polymerization, where its strong acidity and stability under harsh conditions are advantageous.
• Pharmaceutical Intermediate: Serves as a key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring fluorinated components to modulate bioavailability and metabolic stability.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, where the introduction of fluorine atoms enhances product efficacy and environmental persistence.
• Polymer and Material Science: Acts as a monomer or curing agent in the development of high-performance fluoropolymers, ion-exchange membranes, and specialty coatings with superior chemical and thermal resistance.
• Electrolyte Additive: Investigated for use in advanced battery systems, such as lithium-ion batteries, to improve electrolyte stability and performance at high voltages.
• Surface Modification Agent: Utilized to create hydrophobic and oleophobic surfaces on various substrates due to its perfluorinated structure.

Quality Control

Our 1,1,2,3,3,3-Hexafluoro-2-(Trifluoromethyl)Propanesulphonic Acid is manufactured under stringent controls to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including HPLC, NMR, and titration methods, to verify identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature and properties as a strong acid/organic solvent, store in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C (refrigerated) for long-term stability. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
