Manufacturing Quality Control of 288101-48-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient HPLC-UV; identification relies on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration where iodine reacts stoichiometrically with water in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni, Pd) by inductively coupled plasma mass spectrometry after acid digestion and dilution. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and subsequent weighing. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection after sample dissolution and filtration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid sample against defined standards under controlled lighting and white background. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular variation in laser light scattering pattern of dispersed sample in air or liquid medium. |
| Bulk Density | ASTM D1895 | Determines mass per unit volume of freely settled powder using standardized cylinder and tapping procedure. |
| Loss on Drying | Thermogravimetric Analysis | Measures weight loss upon heating (105 C, 2 h) to quantify volatile components including residual solvents and moisture. |
