Properties and stability
Dark brown powder. Odorless. It softens and agglomerates at 175℃, melts and decomposes at 181~188℃, and completely decomposes at 260℃. 1g of product is soluble in 15ml of chloroform, easily soluble in benzene, soluble in oil, fat, paraffin oil, phenol, slightly soluble in ethanol and acetone, and almost insoluble in water. It appears as a slightly purple-red solution in alcohol or benzene. The alcohol solution appears red-purple when exposed to sodium hydroxide. It appears blue-green in sulfuric acid. When diluted, a red precipitate is formed. The maximum absorption wavelength is 520 (357) nm. Irritating.
