Relative Molecular Weight:780.17(according to 1987 Edition of INTERNA-TIONAL MOLECULAR WEIGHT)
Formula:C32H14O6N8S2CuNa2
Physical and Chemical properties
with an appearance of dark blue even powder,it shows yellowish green color in concentrated sulfuric acid and turns greenish blue with blue-green pre-
cipitate afterdilution.ln concentrated nitric acid,it is partly solved presenting light yellow-green color.lt cannot be solved in concentrated caustic sodan,and
appears sky blue in concentrated ammonia.With good solubility in water,its aqueous solution is brilliant blue-colored.lt is slightly sensitive to hard water.
Uses:lt is used for the dyeing of cotton or viscose ibres,fot the printing of cftton or viscose fabrics ,for the dyeing or printing of silk,wool,polyamide and
polyester-viscosebiend fabrics.ltcan be applied to the continuous pad dyeing of cotton cloth.
