Description

Deuterofluorosulfuric Acid is a specialized isotopically labeled derivative of fluorosulfuric acid, where hydrogen atoms are replaced by deuterium. This compound is valued for its role as a powerful superacid and deuterium source in advanced synthetic and analytical chemistry. It is primarily utilized by researchers and process chemists in the pharmaceutical, agrochemical, and materials science sectors for applications requiring precise isotopic labeling or strong acid catalysis under controlled conditions.

Application

• Isotopic Labeling Agent: Used as a deuterium source for the synthesis of deuterated organic compounds and active pharmaceutical ingredients (APIs) in drug discovery and development.
• Superacid Catalyst: Employed in specialized organic synthesis and polymerization reactions that require an exceptionally strong, non-aqueous acidic environment.
• NMR Spectroscopy: Serves as a reagent or solvent in nuclear magnetic resonance (NMR) studies for structural analysis and mechanistic investigations.
• Electrolyte Research: Investigated for use in advanced battery systems and fuel cells due to its unique ionic properties.
• Chemical Intermediate: Acts as a precursor in the synthesis of other deuterated or fluorosulfonated specialty chemicals.
• Academic & Industrial R&D: A critical tool for mechanistic studies, kinetic isotope effect (KIE) experiments, and the development of novel synthetic methodologies.

Quality Control

Our Deuterofluorosulfuric Acid is produced and handled under strict quality protocols to ensure high isotopic purity and chemical integrity, suitable for sensitive research applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic enrichment (D atom %), chemical purity, and impurity profiles. We adhere to cGMP principles where applicable to support our clients in regulated development environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and a strong acid/organic solvent; containers must be kept tightly sealed under an inert atmosphere (e.g., argon or nitrogen) to prevent degradation. Keep away from incompatible materials such as strong bases and oxidizing agents.
