Chemical name

sodium;4-[3-(4-hydroxy-3-methylphenyl)-1,1-dioxo-2,1$l^{6}-benzoxathiol-3-yl]-2-methylphenolate

inChI Key

FMKJVYROEYMYFV-UHFFFAOYSA-M

Solubility

Soluble in water, dilute alcohols, acids, alkalies and ethanol.

pH indicator with color changes for acidic solutions of pH 0.2 (red) to pH 1.8 (yellow), and for basic solutions of pH 7.2 (yellow) to pH 8.8 (red). Used in many common molecular biology reactions in place of other loading dyes. It does not inhibit Taq polymerase to the same degree as other common loading dyes.

Applications:

Cresol Red sodium salt can be used in many common molecular biology reactions in place of other loading dyes. It is used as an pH indicator dye with visual transitions : pH 0.2 (orange)-pH 1.8 (yellow), pH 7.1 (yellow)-pH 8.8 (red). Also used as a constituent of PCR reagent systems.
