Use

2-Nitroaniline may be sensitive to prolonged exposure to light. Mixtures of 2-Nitroaniline with magnesium are hypergolic on contact with nitric acid. 2-Nitroaniline forms extremely explosive addition compounds with hexanitroethane. 2-Nitroaniline has a vigorous reaction with sulfuric acid above 392° F. 2-Nitroaniline is incompatible with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizers.
