Manufacturing Quality Control of ROSOLIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purified Content) | UV-Vis Spectrophotometry | Quantification based on absorbance at characteristic wavelength (e.g., 520 nm) using Beer-Lambert law. |
| Loss on Drying | Gravimetric Analysis (Thermogravimetry) | Mass loss measured after drying at specified temperature (e.g., 105 C) to determine volatile content. |
| Residue on Ignition | Weight Loss on Ignition | Inorganic residue determined after high-temperature ashing and gravimetric measurement. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantitative determination of total heavy metals via flame or graphite furnace AAS after acid digestion. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Titration with silver nitrate using silver indicator electrode; endpoint detected by potential change. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitation as BaSO4 followed by filtration, drying, and weighing of the precipitate. |
| pH of Aqueous Solution | pH Meter Measurement | Direct potentiometric measurement of hydrogen ion activity in a standardized aqueous suspension. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid using calibrated capillary method. |
| Solubility in Water | Visual Observation / Filtration Test | Assessment of complete dissolution in defined volume of water at specified temperature and time. |
| Organic Impurities (Related Substances) | High Performance Liquid Chromatography (HPLC) | Separation and quantification of impurities using reversed-phase C18 column and UV detection. |
| Iron (Fe) Content | Colorimetric Spectrophotometry (1,10-Phenanthroline) | Formation of orange-red Fe(II)-phenanthroline complex measured at ~510 nm. |
| Appearance (Color and Physical Form) | Visual Inspection | Comparison against reference standard for color, crystallinity, and absence of foreign particles. |
