Methyl Red Sodium Salt CAS: 845-10-3 | MF: C15H14N3NaO2 | MW: 291.28, Buy now for reliable and reproducible results from Tristains indicators at Chemical World.
Methyl red sodium salt is provided in the form of reddish-orange powder or solid. It is made by the neutralization of methyl red with sodium hydroxide to form a stable sodium salt without eliminating the azo linkage (-N=N-) that is required. It exhibits high solubility in water and thus, a good indicator solution can be used in a variety of analytical tasks. The chemical composition of Methyl Red Sodium Salt is C15H14N3NaO2. Being a derivative of sodium salt and of methyl red, it is essentially utilized as an acid-base indicator in chemistry. This reagent is used in laboratories that conduct wide concentration titration and analysis testing due to its consistency and reliable performance.
Applications
- Methyl Red Sodium Salt is usually employed as a pH indicator in acid-base titration experiments.
- It is applied in a wide range of analytical methods, including titrimetric analysis and spectrophotometric measurements.
- In microbiological testing, it plays a critical role in the Voges-Proskauer test to identify microorganisms capable of producing stable acids through mixed acid fermentation of glucose.
Key features
- Distinct and Reversible Color Change: Provides precise titration endpoints and a sharp color shift between red and yellow in the pH range of 4.4 to 6.2.
- Very Water-Soluble and Convenient: It is highly soluble in water, and can be ready to use directly in the laboratory and in the field.
- Cost-effective and Multi-Purpose: Ideal in academic, research and industrial laboratories that require routine pH analysis or microbiological tests.
- High Reliability and Batch Consistency: Prepared to high standards of quality to assure purity, stability and reproducible analytical behaviour.

Methyl Red sodium salt is the sodium salt of Methyl Red. Methyl red is an indicator dye that turns red in acidic solutions. It is a pH indicator, turning red under pH 4.4, yellow over pH 6.2, and orange in between those values. It is used in microbiology in the Voges-Proskauer test to identify bacteria that produce stable acids through mixed acid fermentation of glucose. Methyl-red positive bacteria include Proteus vulgaris and Escherichia coli. Methyl-red negative bacteria include Enterobacter aerogenes and Serratia marcescens.
