| Residual Solvents | GC-FID or GC-MS | Headspace gas chromatography with flame ionization detection to quantify residual solvents (e.g., toluene, THF, DMF) based on calibrated external/internal standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Heavy Metals (Pb, Cd, Hg, As, Cr, Ni) | ICP-MS | Multi-element trace metal quantification after microwave-assisted acid digestion, utilizing isotopic detection for sub-pptr sensitivity. |
| Chloride Ion (Cl⁻) | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on an ion-exchange column followed by suppressed conductivity detection; chloride quantified against aqueous calibration standards. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed via visual detection of solid-to-liquid phase change under controlled heating rate (e.g., 1 °C/min). |
| Residue on Ignition (Sulfated Ash) | Gravimetric Analysis | Mass of inorganic residue remaining after controlled high-temperature combustion (~750–800 °C) of sample in platinum crucible. |
| Appearance and Color | Visual Inspection / APHA Color Scale | Subjective assessment of crystalline morphology and comparison of solution color (in specified solvent, e.g., toluene) to standardized APHA color scale. |
| Specific Optical Rotation | [α]D (if chiral impurities suspected) | Measurement of plane-polarized light rotation using sodium D-line (589 nm) in solution; used to detect chiral contaminants or enantiomeric impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity vs. angle to determine volumetric particle size distribution in dispersed solid sample. |
| Bulk Density | ASTM D1895 Method A | Gravimetric determination of mass per unit volume for freely settled powder in a calibrated cylinder. |
| Loss on Drying (LOD) | Thermogravimetric Analysis (TGA) or Oven Drying | Weight loss measured after heating sample at defined temperature (e.g., 105 °C, 2 h) under controlled atmosphere to remove volatile components. |
| Elemental Analysis (C, H, N, Br) | Combustion Analysis (CHNBr Analyzer) | High-temperature oxidative combustion followed by gas chromatographic separation and thermal conductivity detection of CO₂, H₂O, N₂, and halogen-specific detection (e.g., microcoulometric for Br). |
