Manufacturing Quality Control of (2-CARBOXYETHYL)TRIPHENYLPHOSPHONIUM BROMIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Moisture Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generated in situ, based on stoichiometric reaction with water. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., THF, toluene) by gas chromatography with flame ionization detection. |
| Inorganic Halides (Br-) | Ion Chromatography (IC) | Separates and quantifies bromide ions using anion-exchange column and conductivity detection. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element trace metal quantification via inductively coupled plasma mass spectrometry after acid digestion. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (500-600 C) and weighing. |
| Acid Value | Acid-Base Titration | Determines free carboxylic acid groups by titration with standardized NaOH solution using phenolphthalein indicator. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating purity and identity. |
| Organic Impurities (Related Substances) | HPLC-DAD | Detects and quantifies structurally related impurities using HPLC with diode array detection and peak area normalization. |
| Chloride Content | Potentiometric Titration | Quantifies chloride ions using silver nitrate titrant and silver/silver chloride electrode for endpoint detection. |
| Bulk Density | USP <616> Method I | Measures mass per unit volume of powder under controlled tapping conditions using a calibrated cylinder. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular variation in laser light scattering from dispersed particles in air or liquid. |
