Industrial Applications of Methyl Red sodium salt
| Industry | Application | Process |
|---|---|---|
| Chemical Reagents | Acid-base titration indicator | Sodium methyl red is used as a pH indicator in acid-base titrations, with a color-change range of 4.4–6.3 |
| Analytical Chemistry | pH measurement | Used to determine solution acidity or alkalinity, commonly applied in laboratory analysis |
| Biology | Cell staining | Applied as a cell stain in certain biological experiments |
| Education | Chemistry teaching experiments | Used in chemistry laboratory instruction at universities and secondary schools |
Manufacturing Quality Control of Methyl Red sodium salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., 520 nm) and calculates concentration using Beer-Lambert law and certified reference standard. |
| Loss on Drying | Gravimetric Analysis (Thermogravimetry) | Determines volatile content by measuring mass loss after drying at specified temperature (e.g., 105 C) for fixed duration. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metal content via flame or graphite furnace AAS after acid digestion and chelation. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Measures chloride ion concentration by titration with silver nitrate using silver indicator electrode. |
| Sulfate Impurity | Gravimetric Analysis (Barium Sulfate Precipitation) | Precipitates sulfate as BaSO4, filters, dries, and weighs to determine sulfate content. |
| pH of Aqueous Solution | pH Potentiometry | Measures hydrogen ion activity in a defined aqueous solution (e.g., 1% w/v) using calibrated pH meter. |
| Residue on Ignition | Gravimetric Analysis (Ignition Residue) | Determines inorganic ash content by ignition at high temperature (e.g., 600 C) followed by weighing of residual material. |
| Water Content | Karl Fischer Titration | Quantifies water via stoichiometric reaction between water and iodine in presence of SO2, pyridine, and methanol. |
| Iron Impurity | ICP-OES | Measures trace iron after sample digestion using inductively coupled plasma optical emission spectroscopy. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separates and quantifies residual solvents or organic impurities using flame ionization detection. |
| Color Value (APHA) | Visual Comparison or Photometric APHA Measurement | Evaluates yellowness/brownness by comparing to platinum-cobalt standard solutions or measuring absorbance at 455 nm. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using angular scattering pattern of laser beam. |
