This substance, obtained among the products of the reaction of chloride of sulphur on a solution of ammonia, is a solid, colourless, insoluble in water, soluble in alcohol, crystallizing in cubes. It is characterized by producing a fine, but fugitive purple colour, when brought into contact with potash and alcohol.
Dr Gregory obtained from it between 92 and 93 per cent. of sulphur, and from 6 to 7 per cent. of nitrogen.
