Overview / Applications

Outline	This product is for research use only. Do not administer it to human. Green Chemistry Fluorinating Agents Nucleophilic fluorinating agents are widely used in the synthesis of fluorine-containing pharmaceutical intermediates and functional materials. DAST (Diethylaminosulfur Trifluoride) is a typical nucleophilic fluorinating agent. With this reagent, alcohol is substituted by fluorine and difluoride is added to ketone and aldehyde. BAST [Bis (2-methoxyethyl) aminosulfur Trifluoride] is an analogous compound of DAST. It is superior in thermal stability compared to DAST, and is easy to handle. Features Wide range of reactivity - Alcohol (hydroxyl group) is substituted by fluorine atom - Carbonyl group in aldehyde and ketone is substituted by difluoromethylene group References Robins, M.
