Manufacturing Quality Control of 2-CHLORO-3,5-DINITROPYRIDINE
| 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 (e.g., mono-nitro isomers, chloropyridine, dinitropyridine) using gradient HPLC-UV. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration based on iodine consumption in a pyridine-methanol solvent system. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700-800 C to oxidize organic matter; residue weight reflects inorganic ash content. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption measurement after acid digestion and matrix matching; detects total extractable heavy metals. |
| Sulfated Ash | Gravimetric Analysis | Sample charred with sulfuric acid, then ignited at 600-700 C; weight of residual sulfate salts determined. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as solid-to-liquid phase change under controlled heating rate. |
| Organic Volatile Impurities | GC-FID | Headspace or direct injection GC with flame ionization detection for residual solvents (e.g., DMF, toluene, acetone). |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volumetric particle size distribution in dry or wet dispersion. |
| Bulk Density | Tap Density Tester | Mass per unit volume measured after standardized tapping of powder in a graduated cylinder. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
