Manufacturing Quality Control of 847728-89-6
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 220–254 nm, comparing peak area against a certified reference standard. |
| Enantiomeric Excess (ee) | Chiral HPLC | Separation and quantification of (R)- and (S)-enantiomers on a chiral stationary phase, calculating ee from peak area ratio. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., heptane, THF, ethyl acetate) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg, Ni) after acid digestion, with detection limits ≤1 ppm. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content based on stoichiometric reaction. |
| Residual Chloride | Ion Chromatography (IC) | Quantification of chloride ion impurity via suppressed conductivity detection after anion exchange separation. |
| Related Substances | HPLC-UV (Forced Degradation Study) | Detection and quantification of process-related impurities and degradation products using stressed conditions (acid/base/oxidative/thermal/light). |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-phase transition temperature range using calibrated digital apparatus per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity of the solid sample against established reference standards under controlled lighting. |
| Residual Palladium | ICP-OES | Quantification of palladium catalyst residue after microwave-assisted acid digestion, per ICH Q2(R2) validation requirements. |
