| Paper Industry | Used as a paper fluorescent whitening agent to improve apparent whiteness | Incorporated into pulp or surface-sizing agents during papermaking |
| Detergent Industry | Added to detergents as a fluorescent whitening agent to enhance fabric whiteness after washing | Blended with other ingredients in detergent formulations to produce solid or liquid products |
| Analytical Chemistry | Used as a chemical reagent, e.g., as an indicator for metal ion detection | Prepared into specific test solutions for quantitative or qualitative analysis in laboratory applications |
Manufacturing Quality Control of ANS-NA
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against a certified reference standard. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration measuring water content via iodine-sulfur dioxide reaction in methanol-based solvent. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode and pH meter. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Sulfate Impurity | Ion Chromatography | Separation and quantification of sulfate anion using suppressed conductivity detection with carbonate eluent. |
| Chloride Impurity | Argentometric Titration | Titration with standardized silver nitrate solution; endpoint detected potentiometrically or by chromate indicator. |
| Residue on Ignition | Gravimetric Analysis | Mass loss upon high-temperature ashing (700-800 C) followed by weighing of non-volatile residue. |
| Organic Impurities (Related Substances) | HPLC-DAD | Identification and quantification of structurally related compounds using diode-array detection and retention time matching. |
| Iron Content | AAS | Atomic absorption spectroscopy measurement of Fe after sample digestion and dilution in acidic medium. |
| Sodium Content | Flame Photometry | Quantification of Na+ ions based on characteristic emission intensity at 589 nm in air-acetylene flame. |
| Color (APHA) | Visual Comparison or Spectrophotometric | Measurement of yellowness in 1% aqueous solution against APHA color standards using spectrophotometer at 430 nm. |
| Solubility in Water | Gravimetric Dissolution Test | Determination of undissolved residue after stirring 1 g sample in 100 mL water for 30 min at 25 C and filtration. |
