Manufacturing Quality Control of 4-bromo-2,6-dichloropyridine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification via reversed-phase HPLC with UV detection at ~254 nm, using external standard calibration. |
| Residual Solvents | GC-FID | Separation and quantification of volatile organic solvents (e.g., dichloromethane, toluene) using capillary GC with flame ionization detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion by inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration based on iodine consumption in a pyridine–methanol–SO₂ system specific for water. |
| Chloride Impurities (e.g., Cl⁻) | Ion Chromatography (IC) | Separation of anions on a high-capacity anion-exchange column with suppressed conductivity detection. |
| Related Substances (Impurity Profile) | HPLC-UV/DAD | Identification and quantification of structurally related impurities (e.g., mono-chloro, bromo-pyridine derivatives) using gradient HPLC with diode array detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature using calibrated capillary apparatus per USP <741>. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing (600–800 °C) and weighing. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion via light scattering to determine D10, D50, D90 values per ISO 13320. |
| Bulk & Tapped Density | ASTM D6393 | Gravimetric measurement of mass per unit volume before and after standardized mechanical tapping. |
| Organic Volatile Impurities (e.g., residual brominating agents) | GC-MS | Targeted screening and semi-quantitative detection of reactive volatiles (e.g., Br₂, SOBr₂) using gas chromatography–mass spectrometry. |
| Sulfated Ash | Gravimetric Analysis | Determination of inorganic residue after sulfuric acid treatment and incineration at 700–750 °C. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line (589 nm) to assess chiral purity (if applicable; typically negligible but verified). |
