Manufacturing Quality Control of 4-Chloro-5-nitro-2-hydroxypyridine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., isomers, dehalogenated or reduced by-products) via gradient HPLC separation and UV detection. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., DMF, acetone, methanol) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction in pyridine-methanol medium. |
| Heavy Metals | ICP-OES | Measures total elemental impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion using inductively coupled plasma optical emission spectrometry. |
| Chloride Content | Ion Chromatography | Quantifies inorganic chloride ions released during alkaline hydrolysis using suppressed conductivity detection. |
| Nitro Group Content | Redox Titration (with Fe2+) | Determines nitro group concentration via selective reduction to hydroxylamine followed by back-titration of excess ferrous ion with ceric sulfate. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles or discoloration under controlled white light against standard reference. |
| Loss on Drying | Gravimetric Analysis | Determines volatile matter by measuring mass loss after drying at specified temperature (e.g., 105 C) for fixed duration. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
| Bulk Density | Graduated Cylinder Method | Calculates mass per unit volume by gently pouring sample into calibrated cylinder and recording settled volume. |
