Description

Turns red in acidic solutions and used in the MR test to indentify the presence of bacteria. Methyl Red Solution, EP Grade, Reagecon™ is a ready-to-use solution with 50mg methyl red per 100mL. It is manufactured according to Eur. Pharm. Chapter 4 (4.1.1) and prepared in an ISO 9001 facility.

Methyl Red is an azo dye that is a pH indicator that turns color in the presence of acid solutions (red in pH <4.4, yellow in pH >6.2, orange in between). It is particularly used in the MR Test for identifying enteric bacteria that produce stable acids during glucose metabolism (fermentation).
  • Prepared by mixing 50g methyl red in a mixture of 1.86mL of 0.1M sodium hydroxide and 50mL ethanol, and diluted to 100mL with water
  • Manufactured in an ISO 9001-compliant facility according to Eu. Ph. Chapter 4 (4.1.1) guidelines
  • Provided with a certificate of analysis and a label that shows the lot and expiration date
  • Ready to use reagent eliminates the time and labor of preparing precise volumetric solutions
