- Appearance
- Safety A powerful, high explosive as sensitive as picric acid. Forms impact-, friction- or electric shock-sensitive explosive complexes with cysteine and nucleophiles (e.g., potassium hydrogen carbonate in water or methanol, potassium hydroxide in methanol, ammonia, hydroxylamine, hydrazine hydrate). Forms explosive adducts with furan, N-methylindole, and N-methylpyrrole. Forms adducts with ketones (e.g., acetone, cyclopentanone, cyclopentanedione, 2,4-pentanedione, 3-methyl-2,4-pentanedione) which can produce shock-sensitive, high explosive potassium salts. Upon decomposition it emits toxic fumes of NOx. See also EXPLOSIVES, HIGH.
