Manufacturing Quality Control of 2-Aminopyridin-4-ol
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and detection of impurities using gradient HPLC-UV; identification and quantification based on retention time and response relative to main peak. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine water content based on stoichiometric reaction with iodine and sulfur dioxide. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to volatilize organic matter; residue weight measured after cooling in desiccator. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection by inductively coupled plasma optical emission spectroscopy after acid digestion and dilution. |
| Chloride Impurity | Ion Chromatography | Separation of chloride anions on ion-exchange column with conductivity detection, quantified against standard calibration curve. |
| Sulfate Impurity | Turbidimetric Method | Reaction with barium chloride under acidic conditions to form BaSO4 precipitate; turbidity measured spectrophotometrically at 420 nm. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range at which solid transforms to liquid. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Hydrogen ion activity determined using calibrated glass electrode in a 1% w/v aqueous suspension. |
| Organic Volatile Impurities | GC-FID | Separation by gas chromatography and detection via flame ionization detector; quantified against internal standard. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity pattern to calculate volume-based particle size distribution in dispersed slurry. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution at specified concentration and wavelength (e.g., 589 nm). |
