What is of Chloroauricacid with CAS 16903-35-8?
- Chlorine acid is mainly used for alkaloid determination, electroplating gold, photography, gold powder, porcelain coloring, red glass manufacturing, special ink and treatment of tuberculosis. It can also be used as analytical reagent, such as microanalysis of rubidium (Rb) and cesium (Cs). It is used for semiconductor, electronic connector and local gold-plated of integrated circuit lead frame, also for printing circuit boards.
