Toxicity Study No. S.005223.2 19, March 2020 Protocol No. OFMA 92 iv17.03 01S, 2758 70 iv19 04 01F and 49iv19 03 01ETiered In Vitro Toxicity Testing of the Novel Energetic 1 methyl 2,4.5 trinitroimidazole (MTNI)
Abstract
The Army is identifying replacements for substances causing environmental and/or occupational risks. IMTNI was evaluated in several in vitro test systems, including the Ames mutagenicity assay, the Microtox Acute Toxicity Test System, and the human cell line activation test (h-CLAT) for skin sensitization. Data from the h-CLAT were also utilized to predict a Hazard Category for acute oral toxicity. MTNI was found to be extremely toxic in all assays completed, mutagenic in the Ames, and a sensitizer in h-CLAT. The high aquatic toxicity combined with high solubility of MTNI causes concern for environmental and groundwater contamination. Additional aquatic testing should be conducted. Skin contact with MTNI should be avoided.
