98% Cresolo rosso sfuso di fabbrica ISO
Cresolo rosso is a greenish powder, ranging from green to dark green or brown-red, slightly soluble in water and very soluble in ethanol but insoluble in acetone or benzene.
Its color changes from orange to yellow between pH 0.2 and 1.8 and from yellow to purple between pH 7.0 and 8.8.
In Nei laboratori e nelle industrie di protezione ambientale, viene utilizzato come indicatore acido-base, colorante e indicatore bicolore.
Generally, people dilute it to a 0.1% elution or to a 0.04% sodium salt aqueous solution as an indicator.
For example, it is used as a pH-sensitive indicator dye in nano-optical urea biosensor membranes and in heteronuclear-structured fiber-optic pH sensors.
