Manufacturing Quality Control of 119990-81-7
| 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. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification via retention time matching and threshold-based reporting. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., toluene, heptane) by gas chromatography with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-OES | Quantifies metals (e.g., Pb, Cd, Ni, Fe) after acid digestion by optical emission spectroscopy at element-specific wavelengths. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Optical Rotation | Polarimetry | Measures specific rotation at 20 degrees C using sodium D-line light to confirm chiral integrity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution by measuring angular scattering intensity of laser beam. |
| Bulk Density | ASTM D1895 | Determines mass per unit volume of freely settled powder using standardized graduated cylinder and tapping procedure. |
| Loss on Drying | Gravimetric Analysis | Measures weight loss after drying at 105 degrees C for 2 hours under vacuum, indicating volatile and moisture content. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic residue after high-temperature ashing (600-700 degrees C) and weighing. |
