Manufacturing Quality Control of 2-Nitro-3-hydroxypyridine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., unreacted 2-nitropyridine, 3-hydroxypyridine, nitrophenol derivatives) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of residual solvents (e.g., ethanol, ethyl acetate, toluene) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content based on stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element determination of Pb, Cd, Hg, As, and Cr after acid digestion, using inductively coupled plasma optical emission spectrometry. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-750 C followed by weighing of non-volatile inorganic residue after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light and against standard references. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Measurement of mass loss upon heating to 105 C for 2 hours, reflecting volatile content including moisture and low-boiling residues. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode to assess acidic/basic impurities. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light to confirm chiral integrity and absence of racemization (though compound is achiral, detects chiral contaminants). |
