Канцерогенность

Under the conditions of the bioassay, the compound was carcinogenic in male rats inducing transitional cell carcinomas of the urinary bladder (controls 0/15, lowdose 0/46, high dose 11/39). The same tumor was also observed in three dosed female rats and may have been associated with the administration of the chemical. No evidence of carcinogenic activity was found in the mice.

Несовместимости

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. It is unknown if this nitro compound is explosive; some are flammable and explosive, and the contact with alkali increases thermal sensitivity of these materials.
