Description

3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecanesulphonic Acid is a high-purity, long-chain perfluorinated sulfonic acid derivative, valued for its exceptional chemical stability and strong acidic properties. This compound serves as a critical building block and catalyst in advanced material synthesis and specialty chemical manufacturing. It is primarily utilized by R&D laboratories and industrial producers in the electronics, polymer, and pharmaceutical sectors for applications requiring a stable, fluorinated acid source.

Application

• Catalyst and Reagent in Organic Synthesis: Acts as a strong Brønsted acid catalyst for alkylation, acylation, and other acid-catalyzed reactions, particularly where moisture sensitivity is a concern.
• Surface Treatment and Etching: Used in the formulation of specialty etchants and surface modifiers for fluoropolymers and electronic components due to its fluorinated chain.
• Polymer Industry Intermediate: Serves as a key monomer or modifier in the synthesis of ion-exchange membranes, perfluorinated polymers, and other high-performance materials.
• Electrolyte Additive: Investigated for use in advanced battery systems and electroplating baths to enhance conductivity and stability.
• Analytical Chemistry Standard: Employed as a reference standard in chromatographic analysis (e.g., HPLC) and mass spectrometry for quantifying perfluorinated compounds (PFCs).
• Pharmaceutical Research: Utilized in the development of novel drug candidates and prodrugs where a perfluorinated sulfonate group is required for specific biological activity or stability.

Quality Control

Our 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-Heptadecafluorodecanesulphonic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets exacting specifications for research and industrial use. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature and strong acid properties, store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and degradation.
