Manufacturing Quality Control of 4-Biphenylcarboxylic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography. |
| Melting Point | Capillary melting point apparatus | Thermal transition temperature measured by observing the solid-to-liquid phase change under controlled heating. |
| Appearance | Visual inspection | Assessment of physical state, color, and presence of foreign particles under standardized lighting and viewing conditions. |
| Loss on Drying | Gravimetric method (105 C, 2 h) | Mass loss determined after drying under specified temperature and time to assess volatile content and residual solvents. |
| Residue on Ignition | Sulfated ash gravimetry | Non-volatile inorganic residue quantified after high-temperature ignition following sulfuric acid treatment. |
| Chloride Impurity | Ion chromatography (IC) | Separation and quantification of chloride anions using an ion-exchange column and conductivity detection. |
| Sulfate Impurity | Barium chloride turbidimetry | Formation of insoluble barium sulfate precipitate measured spectrophotometrically at 420 nm. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of total heavy metals via flame or graphite furnace AAS after acidic digestion and chelation. |
| Related Substances | HPLC with diode array detection | Identification and quantification of structurally similar impurities using retention time and spectral matching. |
| Water Content | Karl Fischer titration | Electrochemical titration measuring water via iodine-sulfur dioxide reaction in anhydrous methanol-pyridine medium. |
| pH of Aqueous Suspension | Potentiometric pH measurement | pH value determined using calibrated glass electrode in a defined suspension (e.g., 1% w/v in water). |
| Organic Volatile Impurities | Gas Chromatography (GC-FID) | Separation and quantification of residual solvents using capillary column and flame ionization detection. |
