Acid Red 87 CAS 548-26-5

What is Acid Red 87 CAS 548-26-5?

Acid Red 87 CAS 548-26-5 is an organic sodium salt belonging to the class of tetrabromofluorescein dyes. Typically supplied as a red to dark red crystalline powder, it acts as a highly effective fluorochrome and histological dye. While its free acid form is insoluble in water, this commercial disodium salt formulation is highly water-soluble. Due to its intense color yield and distinct chemical properties, it is an essential colorant for a broad spectrum of commercial and laboratory applications.

Specifications

Features
