Manufacturing Quality Control of Sodium 4-hydroxybenzenesulfonate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (purity) | Acid-base titration | Quantifies sodium 4-hydroxybenzenesulfonate by titration with standardized HCl after acidification and back-titration with NaOH. |
| Water content | Karl Fischer titration | Measures trace water via coulometric or volumetric reaction between water and iodine in a methanol-based reagent. |
| pH of aqueous solution | Potentiometric pH measurement | Determines hydrogen ion activity using calibrated glass electrode in a 1% w/v aqueous solution. |
| Heavy metals (as Pb) | Atomic absorption spectroscopy (AAS) | Quantifies total heavy metals by atomization and absorption measurement at characteristic wavelengths after acid digestion. |
| Sulfate impurity | Ion chromatography (IC) | Separates and quantifies sulfate anions based on differential retention on anion-exchange column with conductivity detection. |
| Chloride impurity | Potentiometric titration with AgNO3 | Measures chloride by precipitation titration using silver nitrate and a silver indicator electrode. |
| Residue on ignition | Gravimetric analysis | Determines non-volatile inorganic residue by heating sample at 700-800 C and weighing the ash. |
| Organic impurities (related substances) | High-performance liquid chromatography (HPLC) | Separates and quantifies structurally related compounds using reversed-phase C18 column and UV detection at 254 nm. |
| Iron (Fe) content | Inductively coupled plasma optical emission spectrometry (ICP-OES) | Quantifies iron after microwave-assisted acid digestion by measuring atomic emission intensity at specific wavelength. |
| Appearance (color and clarity) | Visual inspection against standard solutions | Assesses physical state, color (compared to APHA scale), and clarity of a 5% w/v solution in water under controlled lighting. |
| Sodium content | Flame photometry | Measures sodium concentration based on characteristic yellow emission intensity when atomized in air-acetylene flame. |
| Loss on drying | Gravimetric analysis | Determines volatile matter by measuring weight loss after drying at 105 C for 2 hours under atmospheric pressure. |
