| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification via retention time matching and relative response factors. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine, sulfur dioxide, and pyridine-based reagent to determine water content by stoichiometric reaction. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration and subsequent weighing of the residual residue. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) by plasma excitation and emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separation and quantification of sulfate ions using anion-exchange column and suppressed conductivity detection. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Determination of hydrogen ion activity in aqueous solution using calibrated glass electrode and pH meter. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition determination by observing solid-to-liquid phase change under controlled heating rate. |
| Loss on Drying | Thermogravimetric Analysis | Mass loss measurement upon heating under defined temperature and time to assess volatile content including solvents and moisture. |
| Residual Solvents | GC-FID | Quantification of common organic solvents (e.g., methanol, acetone, ethyl acetate) using gas chromatography with flame ionization detection. |
