Manufacturing Quality Control of 1294481-79-0
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~220 nm, comparing peak area against a certified reference standard. |
| Chiral Purity | Chiral HPLC | Enantioselective separation on a chiral stationary phase, measuring % of (2R)-enantiomer relative to total enantiomeric content. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection, quantifying common solvents (e.g., methanol, ethyl acetate, dichloromethane) per ICH Q3C guidelines. |
| 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. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation; stoichiometric reaction with water in anhydrous medium. |
| Related Substances | HPLC-UV (Forced Degradation Study) | Detection and quantification of structurally related impurities (e.g., hydrolysis, oxidation, or isomerization products) under stressed conditions. |
| Residual Chloride | Ion Chromatography (IC) | Separation and quantification of chloride ions using suppressed conductivity detection after sample dissolution and filtration. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by controlled heating; used for identity confirmation and purity screening (sharp range indicates high purity). |
| Specific Optical Rotation | [α]D | Measurement of plane-polarized light rotation in solution at 589 nm; confirms chiral integrity and batch-to-batch consistency. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed particles to determine D10, D50, D90 values, relevant for downstream processing and formulation. |
| Microbial Limits | Membrane Filtration + TSA/TSA+SCDA | Quantitative enumeration of aerobic bacteria, yeasts, and molds per Ph. Eur. 2.6.12/USP <61>. |
| Residual Palladium | ICP-MS | Ultra-trace quantification of Pd catalyst residues post-hydrogenation, critical for pharmaceutical intermediate compliance. |
| Appearance | Visual Inspection | Assessment of color, clarity, and physical form (e.g., white to off-white crystalline powder) under controlled lighting per USP <941>. |
