Chemical Properties
1H-Indazole-5-boronic acid pinacol ester (also known as 5-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indazole) is a light yellow solid powder at room temperature and pressure. It is an indazole compound poorly soluble in water but in common organic solvents, including dichloromethane, chloroform, ethyl acetate, etc. The chemical structure of this compound contains a multifunctional boric acid ester unit and exhibits excellent chemical conversion activity. It can undergo arylation, oxidation, and amination reactions under the catalysis of transition metals, and it has certain applications in synthesising functional organic molecules of indazole.
