Manufacturing Quality Control of 57031-66-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 210-230 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection; relative retention times and spectral matching support qualification. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., methanol, ethyl acetate) based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using mass spectrometry for high sensitivity and low detection limits. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using suppressed conductivity detection after anion exchange column separation. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by sulfuric acid treatment and final weighing to determine inorganic residue content. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using calibrated capillary method per USP <741>. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to assess chiral purity and absence of racemization. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determination of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode system. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion via laser scattering to derive D10, D50, D90 values based on Mie theory. |
| Microbial Contamination | Membrane Filtration | Quantitative recovery and enumeration of aerobic microorganisms using membrane filtration followed by incubation on soybean-casein digest agar. |
