Methyl Red powder Usage and Synthesis.

Methyl Red is used for protozoan live staining, acid-base indicator (pH 4.4to6.2), and clinical serum protein biochemical tests. It has a pH discolouration range of 4.4 (red) to 6.2 (yellow).

It can titrate ammonia, weak organic bases and alkaloids, but is not applicable to organic acids other than oxalic acid and picric acid; it can be used with bromocresol green and methylene blue to form a mixed indicator in order to shorten the colour-changing domain and improve the acuity of colour change.
