Manufacturing Quality Control of THIOFLAVINE S
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with NaOH | Sulfanilic acid derivative reacts quantitatively with standardized NaOH; endpoint detected potentiometrically or with phenolphthalein. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal impurities by measuring absorbance of ground-state atoms in a flame or graphite furnace. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Sample is ignited at 700–800 °C; non-volatile inorganic residue is weighed to determine ash content. |
| Chloride Impurity | Potentiometric Titration with AgNO₃ | Chloride ions react with silver nitrate to form AgCl precipitate; endpoint detected via silver ion-selective electrode. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Sulfate is precipitated as BaSO₄ in acidic medium and quantified by drying and weighing the insoluble residue. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical generation of iodine titrates water stoichiometrically; coulometric method provides high sensitivity for low moisture levels. |
| Organic Impurities | High-Performance Liquid Chromatography (HPLC-UV) | Separation on reversed-phase column followed by UV detection at 254 nm enables identification and quantification of related substances. |
| Melting Point | Capillary Melting Point Determination | Thermal transition is observed visually or automatically as the solid-to-liquid phase change under controlled heating rate. |
| pH of Aqueous Solution | pH Potentiometry | Hydrogen ion activity measured using calibrated glass electrode in a saturated aqueous suspension (1% w/v). |
