Industrial Applications of 2,6-Dichloroindophenol sodium salt
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Oxidation-reduction indicator for vitamin C assay | In acidic medium, sodium 2,6-dichloroindophenol is reduced by ascorbic acid to colorless phenylindamine; the titration endpoint is indicated by the disappearance of pink color, enabling direct volumetric determination of ascorbic acid in food, pharmaceutical, and biological samples |
| Food Testing | Quantitative analysis of vitamin C in fruits, vegetables, beverages, and other food samples | Conforms to GB 5009.86–2016 “National Food Safety Standard – Determination of Ascorbic Acid in Foods”; employs standardized sodium 2,6-dichloroindophenol solution for volumetric titration at pH 3.5–4.0 to minimize interference from coexisting substances |
| Agricultural Research | Determination of ascorbic acid content in plant tissues | Sodium 2,6-dichloroindophenol standard solution is added to the extract (containing metaphosphoric or oxalic acid), followed by spectrophotometric or titrimetric analysis to assess crop antioxidant capacity and post-harvest physiological changes |
Manufacturing Quality Control of 2,6-Dichloroindophenol sodium salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | UV-Vis Spectrophotometry | Measures absorbance at characteristic wavelength (e.g., ~600 nm) and calculates concentration using Beer-Lambert law and reference standard calibration. |
| Related Substances | HPLC with UV detection | Separates and quantifies structurally similar impurities using reversed-phase chromatography and UV detection at appropriate wavelength. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Determines volatile content by measuring mass loss after drying at specified temperature (e.g., 105 C) under controlled conditions. |
| Residue on Ignition | Gravimetric (Sulfated Ash) | Measures non-volatile inorganic residue after high-temperature ignition following sulfuric acid treatment. |
| Heavy Metals | ICP-OES | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg) by plasma excitation and elemental emission spectroscopy. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions via argentometric titration using silver nitrate and a silver indicator electrode. |
| Sodium Content | Flame Photometry | Measures sodium ion concentration based on intensity of characteristic yellow emission in flame. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity in solution using calibrated glass electrode and pH meter. |
| Water Content | Karl Fischer Titration | Quantifies water by coulometric or volumetric reaction with iodine in pyridine/methanol-based reagent. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension using angular scattering pattern of laser light. |
| Microbial Limits | Membrane Filtration and Plate Count | Detects and enumerates viable aerobic microorganisms after filtration and incubation on nutrient agar. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral molecules in solution using sodium D-line source. |
