Chlorophenol red β-D-galactopyranoside (sodium)

Chlorophenol red-β-D-galactopyranoside sodium is a long-wavelength dye, which has been widely used for colorimetric assays. Chlorophenol red-β-D-galactopyranoside sodium is also a β-D-Galactosidase (HY-P2869I) substrate commonly used in recombinant yeast oestrogenic assays[1][2].
