Industrial Applications of Sodium 4-aminosalicylate
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Second-line anti-tuberculosis drug | Serves as a raw material for anti-tuberculosis formulations; used alone or in combination with other anti-tuberculosis agents (e.g., streptomycin, isoniazid) to treat pulmonary and extrapulmonary tuberculosis |
| Pharmaceutical Industry | Therapeutic agent for ulcerative colitis | Serves as a raw material for gastrointestinal therapeutics; used in the treatment of ulcerative colitis and segmental enteritis (Crohn’s disease) |
| Pharmaceutical Industry | Pharmaceutical synthesis intermediate | Used in the synthesis of mesalazine (5-aminosalicylic acid) and other salicylic acid derivatives |
| Dye Industry | Dye intermediate | Used in the synthesis of acid dyes, azo dyes, and ice-color dyes (e.g., as diazo components or coupling components) |
| Chemical Reagents | Analytical reagent | Used for colorimetric determination of iron and copper ions, or as an organic synthesis reagent in laboratory applications |
Manufacturing Quality Control of Sodium 4-aminosalicylate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies sodium 4-amino salicylate by titration with standardized HCl using bromocresol green indicator. |
| Related Substances | HPLC-UV | Separates and quantifies impurities using reversed-phase C18 column and UV detection at 265 nm. |
| Water Content | Karl Fischer Titration | Measures water content volumetrically via iodine reaction with methanol and sulfur dioxide in pyridine-free reagent. |
| Heavy Metals | AAS (Flame or Graphite Furnace) | Determines total heavy metals (e.g., Pb, Cd, As) after acid digestion by atomic absorption spectroscopy. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after incineration at 600-700 C and weighing. |
| Chloride | Argentometric Titration | Quantifies chloride ions by titration with silver nitrate using potassium chromate indicator. |
| Sulfate | Barium Sulfate Gravimetry | Precipitates sulfate as BaSO4 under acidic conditions and determines mass after ignition. |
| pH of Solution | Potentiometric Measurement | Measures hydrogen ion activity in 1% aqueous solution using calibrated pH electrode. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of a 1% w/v solution against water standard. |
| Particle Size Distribution | Laser Diffraction | Determines particle size distribution by analyzing light scattering pattern of dispersed sample. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms and detects specified pathogens using selective culture media. |
| Loss on Drying | Thermogravimetric Analysis | Measures weight loss after drying at 105 C for 2 hours to determine volatile matter. |
