Weak Acid Blue GR
Molecular formula :
MW :
CAS :

nature : blue black powder. Water-soluble solution was purple. Soluble ethanol dark blue solution. Its solution will break down iron case, in boiling heat also caused decomposition metamorphism. Used mainly with silk and wool, are used with nylon, leather. From among sulfanilic acid by diazotization and post-naphthylamine A coupling, and then after the second diazotization and N-p-week acid in acid medium coupling derived.
