CAS No. 223668-64-2 is a high-performance liquid chromatography (HPLC) grade of phenylboronic acid (PBA). It is a white crystalline solid with a melting point of 246-248°C and a molecular weight of 105.98 g/mol. It is soluble in water and acts as a weak acid.
Phenylboronic acid is used as a reagent in a variety of chemical reactions, such as the synthesis of polysaccharides, lipids, and proteins. It is also used as a catalyst in organic synthesis, as a complexing agent for metal ions, and for the modification of polymers and other materials.
Phenylboronic acid is also used in HPLC applications as a chiral selector for the separation of enantiomers. It is also used to control the rate and extent of hydrolysis of glycosides and to catalyze the polymerization of vinyl monomers.
In addition, phenylboronic acid is used in the pharmaceutical industry as a chiral selector for the separation of enantiomers of drugs and other compounds. It is also used as an antioxidant and stabilizer in food products.
Phenylboronic acid is an important intermediate in the synthesis of many organic compounds, such as boronic esters and organoboranes. It is also used in the synthesis of pharmaceuticals, including anti-cancer drugs.
