Natural Methyl Red powder Details
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.

It can also be used as an adsorption indicator for precipitation titration, such as the titration of fluoride ions with thorium nitrate, and can also be used for the determination of free chlorine, chlorite and other oxidants.
Characteristicof Methyl Red powder.
Methyl red appears as lustrous purple crystal or reddish brown powder. Melting point 180-182 ℃. Soluble in ethanol, glacial acetic acid, almost insoluble in water.
Product Method of Bulk Methyl Red powder.
Methyl Red can be obtained by diazotising o-aminobenzoic acid and reacting it with N,N-dimethylaniline.
