Organic Intermediate CAS 525-05-3 is also know as 1-NITROSO-2-NAPHTHOL-3,6-DISULFONIC ACID DISODIUM SALT, Orange Crystalline Powder. Gold crystalline or crystalline powder, slightly soluble in methanol and ethanol. The solution and acidic solution are light yellow, and the alkaline solution is orange yellow. Colorimetric determination of cobalt and potassium is the most sensitive reagent for the determination of trace cobalt. The reagent for the determination of Co, Fe and K is used for the organic synthesis of Ag, Ba, Ca, Co, Fe, Ni, Pb. Prevent the formation of gum in gasoline. Storage conditions: sealing and preservation.
