Manufacturing Quality Control of 151433-25-9
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~280 nm, comparing peak area against a certified reference standard. |
| Chiral Purity | (R,R)-Enantiomeric Excess | Chiral HPLC with chiral stationary phase (e.g., Chiralpak AD-H), measuring relative peak areas of (R,R) and (S,S)/(meso) enantiomers. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., toluene, THF, methanol) based on calibrated external standards. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As, Ni) after acid digestion, using isotopic dilution or external calibration. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying water via iodine generation and stoichiometric reaction with sample moisture. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection by observing solid-to-liquid phase change under controlled heating rate (e.g., 1–2 °C/min). |
| Appearance & Color | Visual Inspection / Hazen/APHA Color Scale | Subjective assessment of physical state (crystalline powder) and color intensity compared to platinum-cobalt standard solutions. |
| Residual Chloride | Ion Chromatography (IC) | Anion exchange chromatography with conductivity detection for quantitative determination of chloride ion from synthesis byproducts. |
| Organic Impurities (Related Substances) | HPLC-UV (Forced Degradation Study) | Detection and semi-quantification of structurally related impurities (e.g., mono-condensation intermediates, hydrolyzed products) under stressed conditions (acid/base/heat/light). |
| Loss on Drying (LOD) | Gravimetric Thermogravimetry (TGA or oven-drying) | Mass loss measurement after drying under specified temperature/vacuum conditions, reflecting volatile content including solvates/moisture. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volumetric particle size distribution in dispersed dry or wet samples. |
| Specific Optical Rotation | [α]D | Measurement of plane-polarized light rotation in solution using a digital polarimeter, confirming chiral integrity and batch consistency. |
| Residual Palladium | ICP-OES | Quantification of palladium catalyst residue after microwave-assisted acid digestion, using plasma emission at characteristic wavelengths (e.g., 340.458 nm). |
