Methyl Orange

Catalog No.: A25006
Azo Dye
Methyl Orange is an azo dye primarily utilized as an acid-base indicator. It exhibits a color change from red at pH 3.1 to bright yellow at pH 4.4, facilitating its application in various pH-related experiments. In addition to its use in acid-base titrations, Methyl Orange is employed for cellular staining and dyeing textiles. Notably, at concentrations of 500 mg/L, it has been shown to exhibit cytotoxic effects and can induce DNA damage, making it relevant for studies in cytotoxicity and genotoxicity.
