Use
2-Nitrophenol is a yellow, crystalline material, moderately toxic, low melting point (45° C). When heated to decomposition 2-Nitrophenol emits toxic fumes of oxides of nitrogen. In molten form violent reaction with strong alkali (85 % potassium hydroxide) [491 M, 1975, p. 342]. Reaction product with chlorosulfuric acid decomposes violently at room temperature [Vervalin, C. H., Hydrocarbon Proc., 1976, 55(9), p. 321].
