설명

일반 설명

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.

애플리케이션

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.

생화학적/생리학적 작용

Methyl Orange is an azo dye which works as a pH indicator.
