| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on iodine consumption in pyridine-methanol solvent system specific for water. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 750 C in platinum crucible, followed by weighing of non-volatile inorganic residue. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, using plasma emission spectroscopy calibrated with matrix-matched standards. |
| Chlorinated Impurities | GC-ECD | Detection and quantification of chlorinated aromatic impurities using gas chromatography with electron capture detection. |
| Related Substances | HPLC-DAD | Separation and identification of structurally related impurities (e.g., aniline, diphenylamine, 3-nitroaniline) using diode array detection. |
| Acid Value | Acid-Base Titration | Titration with standardized KOH ethanol solution using phenolphthalein indicator to determine free acidic impurities. |
| Bulk Density | Graduated Cylinder Method | Measurement of mass per unit volume after controlled tapping per USP <616>. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering principle to determine D10, D50, D90 values. |
| Sulfated Ash | Gravimetric Analysis | Ignition after sulfuric acid treatment to convert metals to sulfates, followed by high-temperature ashing and weighing. |
