Manufacturing Quality Control of Phenylpropiolic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies benzyne carboxylic acid content by neutralizing with standardized NaOH solution using phenolphthalein indicator. |
| Moisture Content | Karl Fischer Titration | Measures water content via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by weighing of residual residue. |
| Heavy Metals | ICP-OES | Quantifies trace metal impurities (e.g., Pb, Cd, Hg) by plasma excitation and elemental emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Related Substances | HPLC-UV | Identifies and quantifies structurally related impurities using reversed-phase chromatography with UV detection at 210 nm. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| Appearance | Visual Inspection | Evaluates physical state, color, and presence of foreign particles under controlled white light against standard reference. |
| Solubility in Common Solvents | Qualitative Solubility Test | Assesses dissolution behavior in solvents such as methanol, acetone, and water by visual observation after agitation. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines acidity of saturated aqueous solution using calibrated pH electrode and meter. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after ignition with sulfuric acid pretreatment. |
| Loss on Drying | Thermogravimetric Analysis | Determines volatile content by measuring mass loss after drying at specified temperature and time under vacuum or nitrogen. |
