Brief Introduction:

N-cyanoacetylurethane, the CAS number is: 6629-04-5, the molecular formula is: C6H8N2O3. The main uses of N-cyanoacetylurethane include as a reference substance in the chemical research of drugs, and for the operation of standard substances such as inspection, identification, content determination, impurity and related substance inspection. In addition, it is also used to check the quality of drugs. As a special measuring tool, it plays a vital role in the research of various drugs.

Preparation Method:

The method for preparing N-cyanoacetylurethane can be achieved by reacting acetylurethane with a cyanating agent (such as thionyl chloride).
