Manufacturing Quality Control of 1-Hydroxy-2-naphthoic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Quantifies carboxylic acid content via neutralization with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or foreign matter against established reference standards. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid, indicating purity and identity based on crystalline structure. |
| Loss on Drying | Gravimetric Method (105 C, 2 h) | Determines volatile content by measuring mass loss after drying under controlled temperature and time conditions. |
| Residue on Ignition | Sulfated Ash Method | Measures inorganic impurities by igniting sample at 700-800 C and weighing residual ash after sulfuric acid treatment. |
| Heavy Metals | Colorimetric Test (Thioglycolic Acid Method) | Detects trace metal impurities (as Pb) by formation of colored metal-thiol complexes under specified pH and heating conditions. |
| Chloride | Silver Nitrate Titration | Quantifies chloride ions by precipitation titration with standardized silver nitrate solution using potassium chromate indicator. |
| Sulfated Ash | Gravimetric Method | Measures total inorganic residue after charring and sulfuric acid treatment followed by high-temperature ignition and weighing. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally similar impurities using reversed-phase chromatography and UV absorbance at 254 nm. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric reaction with iodine, sulfur dioxide, and base in methanol medium. |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Identifies and quantifies residual solvents using capillary column separation and flame ionization detection. |
| Particle Size Distribution | Laser Diffraction Analysis | Measures size distribution of solid particles in suspension by analyzing angular variation of scattered laser light intensity. |
