| Related Substances | HPLC-DAD | Separates and detects structurally related impurities using gradient HPLC coupled with diode array detection for spectral confirmation and quantitation. |
| Residual Solvents | GC-FID | Determines volatile organic solvents (e.g., toluene, DMF, methanol) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in a controlled electrochemical or chemical system. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry for multi-element ultra-trace detection. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid phase under controlled heating, indicating crystallinity and purity. |
| Loss on Drying | Gravimetric Method | Measures weight loss after drying under specified temperature and vacuum conditions to determine volatile and moisture content. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles or discoloration against established reference standards under controlled lighting. |
| Specific Optical Rotation | Polarimetry | Measures the angle of rotation of plane-polarized light induced by chiral molecules in solution, indicating enantiomeric integrity. |
| Residue on Ignition | Gravimetric Ashing | Determines inorganic residue remaining after high-temperature combustion of sample in a muffle furnace, indicating non-volatile inorganic impurities. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension of the compound in water or buffer using calibrated pH electrode. |
