Mercuric amidochloride (HgCl2) is an inorganic compound composed of mercury and chlorine. It is a white solid with a slight yellow tint and a strong odor. It is a strong oxidizing agent and has been used for a variety of industrial, medical, and laboratory applications. In medicine, it is used as an antiseptic, antifungal, and anti-viral agent. In industry, it is used as a catalyst and a bleaching agent. It is also used to make certain types of glass, such as borosilicate glass. It is toxic and should be handled with extreme caution.
