Manufacturing Quality Control of 4-Hydroxy-3-nitropyridine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification and control of known process-related and degradation impurities. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify residual solvents (e.g., methanol, acetone, ethyl acetate) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after anion exchange separation. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by weighing of non-volatile inorganic residue after treatment with sulfuric acid. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature using controlled heating and visual observation of meniscus movement. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against established reference standards. |
| Loss on Drying | Thermogravimetric Analysis | Measurement of mass loss upon heating at 105 C for 2 hours to determine volatile content including absorbed moisture and low-boiling residues. |
| pH of Aqueous Solution | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension using a calibrated glass electrode pH meter. |
| Specific Optical Rotation | Polarimetry | Determination of chiral purity (if applicable) via measurement of rotation angle of plane-polarized light through a solution in a defined cell pathlength. |
