Properties: Monoclinic rhombohedra from alcohol. The commercial crystals (needles) are yellow. mp 80.1°. d420 1.654. Burns at 295° when not confined. Can be distilled under reduced pressure. Vapors are toxic. Dipole moment 1.37. Very sparingly sol in water: About 0.01% at 25°, one gram dissolves in 700 ml of boiling water. Sol in acetone, benzene. Less sol than 2,4,6-trinitrophenol in alcohol, ether, carbon disulfide. Reacts vigorously with reducing agents.
Melting point: mp 80.1°
Density: d420 1.654
CAUTION: Potential symptoms of overexposure are irritation of skin, mucous membranes; liver damage, jaundice; cyanosis; sneezing; coughing, sore throat; peripheral neuropathy, muscle pain; kidney damage; cataract; sensitization dermatitis; leukocytosis; anemia; cardiac irregularities. See NIOSH Pocket Guide to Chemical Hazards (DHHS/NIOSH 97-140, 1997) p 322.
Use: High explosive in military munitions. Must be detonated by a high velocity initiator such as nitramine or by efficient concussion.
