Cresol red is a green to dark green or brown-red, greenish powder slightly soluble in water, and very soluble in ethanol, but insoluble in acetone or benzene.
As its color changes from orange to yellow between pH 0.2-1.8 and yellow to purple between pH 7.0-8.8, it is commonly used as an acid-base indicator, a dye, and a two-color indicator in labs and environment-protection industries.
Generally, it is made into 0.1% etution or 0.04% sodium salt aqueous solution to be used as an indicating agent.
For example, it is used as pH-sensitive indicator dyes in nano-optical urea biosensor membranes and heteronuclear structured fiber optic pH sensors.
