Molecular formula: CH6N4·H2CO3
Structural formula:
Physical property: white and soft
crystal or powder. It is insoluble in alcohol and other
acids and almost insoluble in water. It is unstable while
heating and gradually decomposed when temperature reaches
over 45 °C. Melt point is 170-172 °C. It will be
fully decomposed at 171-173 °C in oil bath.
