DESCRIPTION General description Methyl orange (C.I. 13025) is the sodium salt of p-dimethylaminoazobenzenesulfonic acid.It is an orange-colored synthetic dye, which changes color depending on the pH of the solution. It develops a red color in acidic solution and yellow color in basic solution. Application Methyl orange is used as a- - pH indicator in the cell sap - counterstain to crystal violet in staining pollen tubes - component of a polychrome histological stain - solution indicator, such as in assays of oxalic and malonic acids - in other biomedical applications that include use in film dosimeters and as a reagent for the assay of bromide ions. Biochem/physiol Actions Methyl Orange is an azo dye which works as a pH indicator.[1][2] |
