说明

一般描述

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.
 

应用

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.
