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).

buy Methyl Red powder 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.

Is methyl red hazardous?

May be harmful if swallowed (H303). Call a POISON CENTER or physician if you feel unwell (P312). If inhaled: Remove victim to fresh air and keep at rest in a position comfortable for breathing. If in eyes: Rinse cautiously with water for several minutes.

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.

Methyl red test is used to test fermentative organisms that convert sugars such as glucose into various stable organic acids through the mixed acid pathway. This test is mainly used to differentiate various types of intestinal bacteria, including Salmonella, Escherichia coli, Proteus, and Aeromonas species.

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.

Q: How does Methyl Red differ from Phenolphthalein?
A: Methyl Red detects lower pH ranges (4.4-6.2), while Phenolphthalein works at higher pH (8.3-10).

Q: Is it toxic?
A: Low toxicity but avoid inhalation/ingestion (wear PPE when handling).

Q: Can it be used in schools?
A: Yes – ideal for safe, visible pH demonstrations (diluted solutions).

Q: Do you offer solutions pre-made?
A: Yes – inquire about 0.1% and 0.02% ready-to-use solutions.
