Description

Magic Acid is a superacidic mixture primarily composed of fluorosulfuric acid and antimony pentafluoride, known for its exceptional protonating ability. This powerful reagent is crucial for facilitating challenging chemical reactions, particularly in the protonation of very weak bases and the stabilization of carbocations. It serves as an indispensable tool for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors, enabling the synthesis of novel compounds and the study of reaction mechanisms.

Application

• Catalyst in Organic Synthesis: Used as a superacid catalyst for alkylation, acylation, and isomerization reactions where conventional acids are ineffective.
• Carbocation Chemistry Research: Essential for generating and studying long-lived carbocations and other reactive intermediates in mechanistic studies.
• Pharmaceutical Intermediate Manufacturing: Facilitates key synthetic steps in the production of complex active pharmaceutical ingredients (APIs).
• Polymerization Initiator: Employed in the cationic polymerization of olefins and other monomers to produce specialized polymers.
• Fuel and Petrochemical Research: Applied in hydrocarbon conversion processes and the study of high-octane fuel components.
• NMR Spectroscopy: Used to prepare samples for NMR analysis of unstable species by creating stable ionic solutions.

Quality Control

Our Magic Acid is produced and handled under stringent conditions to ensure batch-to-batch consistency and high reactivity. Quality is verified through analytical techniques including titration and spectroscopic methods to confirm composition and acid strength. A Certificate of Analysis (COA) detailing specific batch parameters is provided with every shipment. We adhere to a cGMP-aligned quality management system to support its use in research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area, away from incompatible materials such as bases, organic materials, and moisture. Due to its highly corrosive and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., argon or nitrogen) to prevent decomposition and maintain potency. Recommended storage temperature is 2-8°C for extended stability.
