Manufacturing Quality Control of 1002355-96-5
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at characteristic wavelength, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities using gradient HPLC-UV, with identification via retention time comparison and peak area normalization. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent where water reacts stoichiometrically to determine trace moisture content. |
| Heavy Metals | ICP-MS | Multi-element detection of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for ultra-trace sensitivity. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection, calibrated with sodium chloride standards. |
| Residual Palladium | ICP-OES | Quantification of palladium residue (e.g., from catalytic hydrogenation) after microwave-assisted digestion, using inductively coupled plasma optical emission spectrometry. |
| Optical Rotation | [alpha]D Measurement | Determination of specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition analysis by observing the temperature range over which solid-to-liquid phase change occurs under controlled heating rate. |
| Loss on Drying | Gravimetric Analysis | Weight loss measured after drying under specified temperature and vacuum conditions to determine volatile and moisture content. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution in dry powder form using laser scattering principles and Mie theory-based calculation. |
| Residual Tert-Butyl Alcohol | GC-FID | Quantification of residual t-butanol (from incomplete deprotection or synthesis) by headspace GC-FID using calibrated external standards. |
