Manufacturing Quality Control of 2,5-Dichloro-3-nitropyridine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities by gradient HPLC-UV, using a C18 column and external standard calibration. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, DMF) based on retention time and peak area. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine water content via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion, using plasma excitation and atomic emission detection. |
| Chloride Ion Impurity | Ion Chromatography | Separation and quantification of Cl- anions on an anion-exchange column with suppressed conductivity detection. |
| Nitro Group Content | Redox Titration | Back-titration of excess sodium nitrite after diazotization under acidic conditions, followed by iodometric determination. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the solid-to-liquid phase change in a calibrated capillary tube. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against standard references. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate volume-based particle size distribution in dry or wet dispersion. |
| Bulk Density | Graduated Cylinder Method | Mass per unit volume measured by gently pouring sample into a calibrated cylinder and recording settled volume. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying at 105 C for 2 hours under vacuum or forced-air oven, indicating volatile matter content. |
