Industrial Applications of 8-Anilino-1-naphthalenesulfonic acid magnesium salt
| Industry | Application | Process |
|---|---|---|
| Dye Manufacturing | Used as an intermediate for acid dyes and reactive dyes, employed in the synthesis of azo dyes (e.g., Acid Blue 25, Acid Black 1) | Produced via diazotization-coupling reaction, coupling with diazotized aromatic amines in a weakly acidic medium to yield the target dye |
| Textile Dyeing and Printing | Applied as a dyeing auxiliary to enhance the affinity and leveling properties of certain acid dyes toward protein fibers such as wool and silk | Added to the dye bath alongside the dye to adjust pH and facilitate dye-fiber bonding |
| Paper Manufacturing | Used as an intermediate for paper colorants, imparting specific hues (e.g., blue or black shades) to paper | Condensed with aldehydes, followed by oxidation to yield colorant resins, which are then applied in pulp dyeing |
Manufacturing Quality Control of 8-Anilino-1-naphthalenesulfonic acid magnesium salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at characteristic wavelength, calibrated against certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content based on the stoichiometric reaction of iodine with water in a methanol-based reagent. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification by ionization in plasma and mass spectrometric detection with high sensitivity and low detection limits. |
| Residual Solvents | GC-FID | Separation and quantification of volatile organic solvents using gas chromatography with flame ionization detection. |
| Chloride Impurity | Ion Chromatography | Anion separation on ion-exchange column with conductivity detection, calibrated for chloride ion concentration. |
| Sulfate Impurity | Gravimetric Analysis | Precipitation of sulfate as barium sulfate followed by filtration, drying, and weighing of the precipitate. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination using calibrated glass electrode and pH meter in a defined aqueous suspension or solution. |
| Iron Content | AAS | Atomic absorption spectroscopy measurement of iron after acid digestion and nebulization into acetylene-air flame. |
| Loss on Drying | Thermogravimetric Analysis | Mass loss measured upon heating at specified temperature (e.g., 105 C) under controlled atmosphere to determine volatile content. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity pattern to calculate particle size distribution in dispersed sample. |
| Organic Volatile Impurities (Total) | GC-MS | Screening and semi-quantitative assessment of unknown organics using gas chromatography coupled with mass spectrometry. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution of the compound at specified concentration and wavelength. |
