Properties: On heating with fuming sulfuric acid (30% SO3) at 100° yields a dark powder, sol in water or alc with bluish-black coloration, used as dyestuff for wool. On heating with molten potassium hydroxide at 190° and oxidizing the reaction product with sodium hypochlorite, an olive-green vat dye is obtained.
Use: In the textile industry; in the determination of boron: Beckett, Webster, Analyst 68, 306 (1943), C.A. 38, 38 (1944).
