Manufacturing Quality Control of 1-Naphthol-5-sulfonic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies 1-naphthol-5-sulfonic acid content by neutralization with standardized NaOH solution using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Titration | Determines water content based on stoichiometric reaction of iodine with water in a methanol-based reagent. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated pH electrode. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies total heavy metals after wet digestion by measuring absorbance of atomic vapor at characteristic wavelengths. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic residue after ignition at 700-750 C following sulfuric acid treatment. |
| Chloride Impurity | Argentometric Titration | Measures chloride ions by titration with standardized silver nitrate solution using potassium chromate indicator. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) | Separates and quantifies impurities using reversed-phase C18 column and UV detection at 254 nm. |
| Iron Content | Colorimetric Spectrophotometry (1,10-phenanthroline) | Forms orange-red complex with Fe2+; absorbance measured at 510 nm after reduction with hydroxylamine. |
| Sulfuric Acid Residue | Acid-Base Titration | Titrates residual free sulfuric acid in sample solution with standardized NaOH using methyl orange indicator. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated melting point apparatus. |
| Organic Volatile Impurities | Gas Chromatography (GC) | Detects and quantifies volatile organic impurities using flame ionization detector and appropriate capillary column. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Evaluates yellowness intensity of 5% aqueous solution against APHA platinum-cobalt standard scale. |
