Manufacturing Quality Control of 148901-69-3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at characteristic wavelength, comparing peak area to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities by gradient HPLC separation and UV response relative to main peak. |
| Residual Solvents | GC-FID | Measures volatile organic solvents using gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration based on iodine consumption in pyridine/methanol buffer. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) by inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Residual Catalyst (Pd) | ICP-OES | Measures palladium residue by inductively coupled plasma optical emission spectroscopy following microwave-assisted digestion. |
| Optical Rotation | [alpha]D Measurement | Determines specific rotation using sodium D-line light in solution to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range of solid-to-liquid transition using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under standardized white light and viewing conditions. |
| pH of Aqueous Suspension | pH Meter | Determines acidity/basicity of a defined suspension in water using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension by measuring angular variation of scattered laser light. |
