| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~275 nm, comparing peak area against a certified reference standard. |
| Identity Confirmation | FT-IR Spectroscopy | Verification of molecular structure by matching characteristic absorption bands (e.g., O–H stretch, aromatic C=C, cyclohexyl C–H) to reference spectrum. |
| Residual Solvents | GC-FID | Separation and quantification of volatile organic solvents (e.g., toluene, ethyl acetate) using capillary GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine/methanol solvent system. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion, leveraging high sensitivity and isotopic resolution for trace metal impurities. |
| Chlorinated Impurities | GC-ECD | Selective detection of chlorinated by-products (e.g., chlorophenols) via electron capture detection following GC separation. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid–liquid phase transition temperature range using calibrated thermal ramp under controlled atmosphere. |
| Specific Optical Rotation | [α]D | Measurement of rotation angle of plane-polarized light at 589 nm to confirm chiral integrity and absence of racemization. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile inorganic residue after high-temperature ashing (500–600 °C) in a platinum crucible. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of surface acidity/basicity via pH electrode in saturated aqueous suspension (1% w/v, 25 °C). |
