Products Description of Molybdenum trioxide CAS#1313-27-5

Molybdenum trioxide is an inorganic compound with the chemical formula MoO3. It is mainly used to determine protein, phenol, arsenic, lead, bismuth, etc. It can also be used as a reducing agent for phosphorus pentoxide, arsenic trioxide, hydrogen peroxide, phenol and alcohols. It can also be used to prepare molybdenum salts and molybdenum alloys.

On October 27, 2017, the World Health Organization's International Agency for Research on Cancer published a preliminary list of carcinogens for reference. Molybdenum trioxide is on the list of Class 2B carcinogens.
