Manufacturing Quality Control of 26638-66-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 220-254 nm, based on peak area comparison against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; individual impurities reported relative to main peak using external standard or area normalization. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection for identification and quantification of volatile organic solvents per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via electrochemical or stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element detection and quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on mass-to-charge ratio detection. |
| Chloride Content | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection, calibrated against sodium chloride standards. |
| Sulfur Content | Combustion IC | High-temperature combustion followed by ion chromatographic analysis of sulfate species to determine total organic and inorganic sulfur. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement using calibrated capillary apparatus; onset and range recorded per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light against defined reference standards. |
| Residue on Ignition | Gravimetric Analysis | Weighed sample ignited at 600-800 C, cooled, and reweighed to determine non-volatile inorganic residue as percentage of original mass. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light through a solution; used to confirm chiral integrity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample using Mie theory to calculate volume-based particle size distribution across D10, D50, D90. |
