Manufacturing Quality Control of 3-METHYL-4-HYDROXYPYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., starting materials, isomers, degradation products) using gradient HPLC-UV with suitable column and mobile phase. |
| Water Content | Karl Fischer Titration | Determines trace water by electrochemical titration with iodine generated in situ, based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing and weighing. |
| Heavy Metals | ICP-OES | Quantifies elements such as Pb, Cd, Hg, As, and Cr by plasma excitation and elemental emission spectroscopy. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic sulfate residue after ignition with sulfuric acid treatment and final weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against established visual standards under controlled lighting. |
| Solubility | Qualitative Solubility Test | Evaluates dissolution behavior in specified solvents (e.g., water, ethanol, methanol) per pharmacopeial guidelines. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a defined aqueous suspension or solution using calibrated pH electrode. |
| Loss on Drying | Thermogravimetric Analysis | Determines volatile content by measuring mass loss after drying at specified temperature and time under controlled atmosphere. |
