Manufacturing Quality Control of 3-HYDROXY-4-PYRIDINECARBOXYLIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~260 nm. |
| Related Substances | HPLC-UV | Separation and detection of structurally related impurities (e.g., isonicotinic acid, 3-oxoisonicotinic acid) using gradient HPLC with UV detection. |
| Loss on Drying | Gravimetric (105 C, 2 h) | Mass loss measured after drying under controlled temperature and time to determine volatile content including residual solvents and moisture. |
| Residue on Ignition | Sulfated Ash (500-600 C) | Weight of non-volatile inorganic residue remaining after charring and high-temperature ignition of the sample. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, Hg, As, Cr) following acid digestion and plasma excitation/emission spectroscopy. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determination of chloride ions by titration with silver nitrate using a silver indicator electrode and endpoint detection via potential change. |
| Sulfate Content | Turbidimetry (BaCl2 method) | Formation of barium sulfate precipitate in acidic medium; quantification via measurement of turbidity at 420 nm. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs, indicating purity and identity. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution at specified concentration and wavelength (e.g., Na D-line). |
| pH of Aqueous Solution | pH Meter (1% w/v suspension) | Electrochemical measurement of hydrogen ion activity in a standardized aqueous suspension to assess acidity/basicity profile. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to determine volumetric particle size distribution in a dispersed slurry. |
