Methyl Red sodium salt Chemical Properties,Usage,Production

  • Chemical Properties orange powder
  • Uses Methyl Red sodium salt is used as a pH indicator. In microbiology, it is used to make agar plates in bacteriology. Further, it is used as a coloring agent and also finds use in mouthwash, toothpaste and in cosmetics. It is also employed as a rocket propellant. In addition to this, it is used in the preparation of reversible stain for rapid detection of stained cells in each specimen.
  • General Description Methyl red sodium salt is the sodium salt of methyl red synthetic dye, which belongs to the azo group of dyes.
  • Biochem/physiol Actions Methyl Red is a pH indicator and it changes color at a pH of 5.5.
  • Purification Methods It can be precipitated from aqueous solution as the free acid which is recrystallised from 95% EtOH, then reconverted to the sodium salt. In H2O it is pink at pH 4.2 and yellow at pH 6.2 and has at 437nm.
