| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210-220 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., 4-bromopiperidine, brominated dimers) using gradient HPLC and UV detection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generation in pyridine/methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (500-600 C) and weighing. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other regulated metals via plasma excitation and elemental emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Turbidimetric Method | Measures sulfate as barium sulfate precipitate formed in acidic medium, quantified by light scattering. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity in 1% w/v aqueous solution using calibrated glass electrode. |
| Melting Point | Capillary Melting Point Apparatus | Observes temperature range at which solid transitions to liquid under controlled heating rate. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral compound in solution using sodium D-line. |
| Loss on Drying | Thermogravimetric Analysis | Determines volatile content by weight loss upon drying at 105 C for 2 hours under vacuum or air. |
| Microbial Limits | Membrane Filtration and Plate Count | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration after incubation. |
