Anaranjado de metilo
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.
- 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
