279261-81-3 - Introduction
acid is an organic compound with the chemical formula C8H9BCl03.
Nature:
acid is a solid powder, colorless or yellowish. It is hygroscopic and readily soluble in many organic solvents, such as alcohols and ethers. It is a moderately strong base-stable boric acid with electrophilic properties.
Use:
azo acid is a commonly used organic synthesis intermediates and reagents. It is commonly used in Suzuki coupling reactions in organic synthesis reactions for the construction of carbon-carbon bonds. It can also be used in the preparation of pharmaceuticals, pesticides and other organic compounds.
Method:
The method for preparing aryl acid is generally to react boric acid and the corresponding halogenated aromatic hydrocarbon to generate aryl borate, and then react with ethanol to generate the target product.
Safety Information:
acid is relatively stable at room temperature, but may decompose at high temperature, direct sunlight or in contact with strong oxidants. It is irritating to the eyes and skin and should be handled with appropriate personal protective equipment. Avoid contact with fire and combustibles during use and storage.
