Manufacturing Quality Control of 155697-42-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 280 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separates and quantifies impurities using gradient HPLC-UV; individual impurities are reported relative to the main peak area. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., methanol, ethyl acetate) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration based on iodine consumption in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-OES | Quantifies total heavy metals (Pb, Cd, Hg, As, etc.) after acid digestion by measuring elemental emission intensities at characteristic wavelengths. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Determines inorganic residue after high-temperature combustion (700-750 C) followed by weighing of the cooled ash. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and purity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white-light illumination against standard references. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension using angular scattering pattern of laser light. |
