Applications

Methyl Red free acid is widely utilized in research focused on:

  • pH Indicator: Commonly used in titrations, it changes color at a pH range of 4.4 to 6.2, making it ideal for determining the acidity of solutions in laboratories.
  • Biological Research: Employed in microbiological studies to differentiate between acid-producing and non-acid-producing bacteria, aiding in the identification of various microbial species.
  • Textile Industry: Used as a dye in textiles, providing vibrant colors while being relatively easy to apply and fix, enhancing the aesthetic appeal of fabrics.
  • Pharmaceutical Applications: Acts as a pH-sensitive dye in drug formulation, helping to ensure that medications maintain their stability and efficacy under varying pH conditions.
  • Environmental Testing: Utilized in assessing water quality, where it helps indicate the acidity of water samples, contributing to environmental monitoring efforts.
