| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with HCl | Quantifies free base content by titration with standardized hydrochloric acid using bromocresol green indicator. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric reaction between water and iodine in pyridine/methanol medium. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content after high-temperature incineration and weighing of residual solids. |
| Heavy Metals | ICP-OES | Quantifies trace metal impurities (e.g., Pb, Cd, Ni) via atomic emission spectroscopy after acid digestion. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate using a silver indicator electrode. |
| Related Substances | HPLC with UV Detection | Separates and quantifies structurally similar impurities using reversed-phase C18 column and UV absorbance at 210 nm. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| pH of Aqueous Solution | pH Meter Measurement | Determines acidity/basicity of a defined aqueous solution (e.g., 5% w/v) using calibrated pH electrode. |
| Loss on Drying | Thermogravimetric Analysis | Quantifies volatile matter by weight loss after drying at specified temperature (e.g., 105 C) under vacuum or air. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile sulfate residues after ignition with sulfuric acid pretreatment. |
| Organic Volatile Impurities | GC-FID | Identifies and quantifies residual solvents (e.g., methanol, acetone) using flame ionization detection. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using Mie scattering theory. |
