| Specification: |
Diazomethane ,its cas register number is 334-88-3. It also can be called Methane, diazo- ; and Azimethylene . It is one of the more common diazo compounds, and it is a popular methylating agent in the laboratory, but it is too hazardous. Diazomethane (CAS NO.334-88-3) can be treated with an excess of benzoic acid in cold Et2O. It is toxic by inhalation or by contact with the skin or eyes (TLV 0.2ppm) and explodes when heated beyond 100 °C. |
