5-Bromo-2,2-difluoro-1,3-benzodioxole

5-Bromo-2,2-difluoro-1,3-benzodioxole is an industrial chemical that can be used in the production of cuprous cyanide. It is made by reacting methanol with hydrogen fluoride and catalysts. The product yield is high and the reaction process is efficient. 5-Bromo-2,2-difluoro-1,3-benzodioxole can be used to produce 1-4c alkyl cyanides by esterification. The catalyst for this reaction is typically a fluoride salt or a metallic salt such as zinc chloride or ferric chloride. This chemical can also be used to produce cyanide from hydrogen cyanide or hydrocyanic acid. The large scale process flow for this chemical involves use of a catalyst, such as sodium hydroxide, potassium hydroxide, or calcium oxide.

5-Bromo-2,2-difluoro-1,3- benzodioxole is used as a precursor in organic synthesis. It is used to prepare 5-bromo-2,2-difluoro-1,3-benzodioxole-4-carboxylic acid. It serves as an intermediate in active pharmaceutical ingredients, agrochemicals and in dyestuff field.
