Reichardt′s dye
Reichardt′s dye belongs to the class of azo merocyanine dyes. Reichardt′s dye, also known as ET(30) or pyridinium N-phenoxyde betaine dye is a highly solvatochromic betaine dye useful for determining solvent polarity effects. It plays an important role as a probe of solvent polarity in biological systems and on surfaces. Reichardt’s dye, a solvatochromic betaine dye has been used for the determination of solvent polarity.
