Objective:
To study the acute, subacute and subchronic toxicity induced by ammonium dinitramide (ADN), and to ascertain the gradation and target organs of acute toxicity induced by AND.
Methods:
According to technical specifications for toxicity determination of chemicals, the oral tests for acute, subacute and subchronic toxicity induced by AND were performed for 90 days.
Results:
The oral LDx for mouse and rat was 568.9 mg/kg and 616.6 mg/kg ADN respectively. The gradation of acute toxicity induced by AND was low level. The results of oral subacute and subchronic toxicity tests (for 28 and 90 days) showed that a gain in weight in group exposed to 123 mg/kg AND was significantly lower than that in control group (P<0.05), the TBIL and ALT in group exposed to 61.6 and 123 mg/kg AND significantly increased and the ratio of liver weight to body weight obviously decreased, as compared with control group, the number of animals with hepatic pathological changes in group exposed to 61.6 and 123 mg/kg AND was significantly higher than that in control group (P<0.05).
Conclusion:
The gradation of acute toxicity induced by ADN was low level. When the exposure dose of AND was 30.8 mg/kg, the adverse effect was not observed, and the target organ was liver.

1° Amines to Diazonium or Aryldiazonium Salts: Diazotization with NaNO2 Overview
The nitrous acid is unstable. Hence, it is formed in situ from a solution of sodium nitrite and cold aqueous acids such as hydrochloric or sulfuric acid. In an acidic solution, the –OH group of nitrous acid undergoes protonation to give oxonium ion, followed by water loss...
