Physicochemical properties (the following information is for reference only): white or light grayish yellow crystal. It is easily soluble in water. When the aqueous solution meets with metal salts, it generates water-soluble non-ferrous compounds, which are slightly soluble in ethanol and insoluble in acetone. The aqueous solution should be colorless, and it will become invalid if it changes color after long-term storage. Below pH 5, it complexed with ferric chloride to form a dark blue solution, orange with titanium salt, green yellow with copper salt, and canary yellow with hexavalent molybdenum

Usage: This product is only for scientific research, and cannot be used for other purposes. It is a photometric reagent for titanium, iron and molybdenum. Complexometric titration of iron. Metal masking agent
