← Multiple images can slide left and right →
CAS No.: 7722-84-1
Molecular formula: H2O2
Molecular weight: 34.01
Structural formula: 
Ultra-clean and high-purity electronic-grade hydrogen peroxide is a very important high-purity reagent in the microelectronics industry. It is mainly used as a semiconductor silicon wafer cleaning agent, etchant and photoresist remover, and can also be used for the preparation of advanced insulating layers. Removal of inorganic impurities in electroplating solutions, treatment of copper, copper alloys, gallium, and germanium in the electronics industry, and etching and cleaning of solar silicon wafers. During the processing, the impurities in the reagent will have a fatal impact on the performance of the components. Therefore, the ultra-clean and high-purity hydrogen peroxide has very strict requirements on the purity.
