Manufacturing Quality Control of Benzyltriphenylphosphonium bromide
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at characteristic wavelength. |
| Related Substances | HPLC-UV | Separates and quantifies impurities based on retention time and peak area relative to main peak. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents by gas chromatographic separation and flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in anhydrous methanol/pyridine medium. |
| Inorganic Halides (as Br-) | Ion Chromatography | Separates and quantifies bromide ions using anion-exchange column and conductivity detection. |
| Heavy Metals | ICP-OES | Determines total elemental impurities (e.g., Pb, Cd, Hg, As) by plasma excitation and optical emission spectroscopy. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized lighting and viewing conditions. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension of sample in water or buffer. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in intensity of scattered laser light. |
| Bulk Density | Tap Density Tester | Determines mass per unit volume after standardized mechanical tapping of a powder sample in a graduated cylinder. |
