Usage

Description

CELESTINE BLUE is a cationic dye characterized by its red light navy blue color with a faint reddish tinge. It is known for its solubility in water, resulting in a red light purple color, and its slight solubility in ethanol, which produces a blue color. In concentrated sulfuric acid, it appears as Daisy blue, turning magenta upon dilution. When mixed with a dye aqueous solution and sodium hydroxide, it forms a blue purple and blue precipitation. CELESTINE BLUE is also described as a black powder.
