CAS 7789-09-5
:Ammonium dichromate
Description:
Ammonium dichromate, with the chemical formula (NH4)2Cr2O7 and CAS number 7789-09-5, is a bright orange crystalline solid that is highly soluble in water. It is primarily used in various applications, including as a reagent in organic synthesis and as a catalyst in chemical reactions. This compound is known for its strong oxidizing properties, which can lead to vigorous reactions, especially when heated. Upon decomposition, it releases toxic chromium(VI) compounds and nitrogen gases, making it hazardous to handle. Ammonium dichromate is also classified as a carcinogen due to the presence of hexavalent chromium, necessitating strict safety precautions during its use. In addition to its chemical applications, it has been historically used in pyrotechnics and as a demonstration of exothermic reactions in educational settings. Due to its environmental and health risks, the use of ammonium dichromate is regulated in many countries, and safer alternatives are often recommended in laboratory and industrial practices.
