Applications

Methyl orange is widely utilized in research focused on:

  • pH Indicator: Commonly used in titrations, it changes color from red to yellow as the pH shifts from acidic to neutral, making it a reliable choice for chemists in laboratories.
  • Textile Industry: Employed as a dye, it provides vibrant colors for fabrics, enhancing the aesthetic appeal of clothing and home textiles.
  • Food Industry: Used as a food colorant, it helps in achieving specific hues in products, although its use is regulated in many countries due to safety concerns.
  • Biochemical Research: Serves as a model compound in studies related to azo dyes, aiding researchers in understanding dye degradation and environmental impact.
  • Educational Purposes: Frequently used in chemistry education to demonstrate acid-base reactions, helping students visualize chemical changes in real-time.
