Manufacturing Quality Control of 142782-22-7
| 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-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3A/B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify common solvents (e.g., methanol, acetone, DMF) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine trace water content via stoichiometric reaction. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, with detection at sub-pptr levels. |
| Chloride Content | Potentiometric Titration | Titration with silver nitrate using a silver indicator electrode; endpoint detected by potential inflection corresponding to AgCl precipitation. |
| pH of Aqueous Solution | pH Meter Measurement | Direct measurement of 1% w/v aqueous suspension using calibrated pH meter with glass electrode. |
| Loss on Drying | Gravimetric Thermogravimetry | Weight loss measured after drying at 105 C for 2 hours under controlled atmosphere, indicating volatile content and residual moisture. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, assessed by visual observation in capillary tube under controlled heating rate. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering to obtain D10, D50, D90 values per ISO 13320. |
| Bulk Density | ASTM D1895 Method A | Measurement of mass per unit volume for freely settled powder in a standardized cylinder. |
| Microbial Contamination | Membrane Filtration & Plate Count | Enumeration of aerobic microorganisms and absence testing for specified pathogens per USP <61> and <62>. |
