Manufacturing Quality Control of Pyridine-N-oxide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration based on the reaction of iodine with water in a methanol-based reagent, measuring endpoint potentiometrically. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C in a platinum crucible, then weighing the non-volatile residue after cooling in a desiccator. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other metals after acid digestion, using plasma excitation and optical emission detection. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions on an anion-exchange column with suppressed conductivity detection. |
| Sulfate Impurity | Barium Sulfate Gravimetry | Precipitation of sulfate as BaSO4 in acidic medium, followed by filtration, ignition, and gravimetric measurement. |
| Related Substances | HPLC-DAD | Identification and quantification of impurities (e.g., pyridine, N-oxide degradation products) using HPLC with diode-array detection and reference standards. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature using calibrated capillary apparatus under controlled heating rate. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a 1% w/v aqueous solution using a calibrated glass electrode pH meter. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting conditions. |
| Solubility in Water | Qualitative Solubility Test | Observation of complete dissolution of 1 g sample in 10 mL distilled water at 25 C with gentle agitation for 5 minutes. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measurement of mass loss upon heating to 105 C for 2 hours under dry air or nitrogen, reporting weight percent loss. |
