Test Specification...BP
Characters A colourless or slightly pinkish-grey, crystalline powder or crystals, turning red on exposure to light and air.
Identification Test (A) Test (B) Test (C) (a) Melting Point (109°C to 112°C.) (b) An intense, deep-red colour develops which becomes pale yellow on the addition of a slight excess ofhydrochloric acidR (c) The solution shows an intense green fluorescence.
Solubility Very soluble in water and in alcohol
Solution S Specified Test
Appearance of solution Solution S is clear (2.2.1) and not more intensely coloured than reference solution B5or R5(2.2.2, Method II) and remains so when heated in a water-bath for 5 min.
