Description

Application
Methyl red is widely used in the Methyl Red (MR) test which is part of the IMViC series of tests to identify bacteria. It helps determine whether a microorganism ferments glucose to produce stable acids indicating a mixed-acid fermentation pathway. It is also used in laboratory research to observe changes in pH during chemical reactions.

Purpose
For R&D

General Description
Methyl red is a pH indicator dye that is commonly used in microbiology and chemistry. It appears red in acidic conditions (pH below 4.4) and yellow in basic or neutral conditions (pH above 6.2). This compound is primarily used to test for the presence of acid-producing bacteria.
