5-bromo-1H-indazole (5-BIA) is an indazole compound that can be used as a raw material in organic synthesis for the preparation of compounds such as 5-Iodo-1H-indazole and 3,5-Dibromo-1H-indazole. 5-BIA and its derivatives (7-BIA) can also be used as a highly effective corrosion inhibitor for copper and the protective ability of 5-BIA is more prominent than that of 7-BIA. 5-BIA and its derivatives (7-BIA) can also be used as highly efficient corrosion inhibitors for copper, and 5-BIA has a more prominent protective ability than 7-BIA. 1.5 mM 5-BIA and 1.5 mM 7-BIA have corrosion inhibition efficiencies (ηE) as high as 97.1 % and 94.0 %, respectively[1]. | [Synthesis]
In a dry 500 mL reaction flask, NaNO2 ( 3.89 g , 56.3 mmol) and water ( 10 m L ) were sequentially added to an acetic acid solution ( 300 mL ) of 4-bromo-o-toluidine ( 10.5 g , 56.3 mmol). The resulting reaction mixture was stirred at room temperature | [References]
