Manufacturing Quality Control of 165727-45-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210-220 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities (e.g., diastereomers, dechlorinated or hydrolyzed derivatives) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, ethyl acetate, toluene) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration with iodine generated electrochemically or added reagent, based on stoichiometric reaction with water. |
| Optical Purity (Enantiomeric Excess) | Chiral HPLC-UV | Resolves (1S,2S) enantiomer from (1R,2R), (1S,2R), and (1R,2S) diastereomers using chiral stationary phase and UV detection. |
| Heavy Metals | ICP-MS | Quantifies trace elements (Pb, Cd, Hg, As, Ni) after acid digestion by inductively coupled plasma mass spectrometry with isotopic detection. |
| Residual Palladium | ICP-MS | Specifically measures palladium residue from catalytic hydrogenation steps using isotope-dilution ICP-MS for high sensitivity and accuracy. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions via suppressed conductivity detection after aqueous extraction of sample. |
| Residual Benzyl Chloride | GC-MS | Identifies and quantifies unreacted benzyl chloride precursor by gas chromatography coupled with mass spectrometric detection. |
| Particle Size Distribution | Laser Diffraction | Measures dry powder particle size distribution using Mie scattering theory applied to laser light diffraction patterns. |
| Melting Point | DSC | Determines onset and range of melting transition by differential scanning calorimetry under controlled heating rate. |
| Appearance and Color | Visual Inspection / Hazen Scale | Assesses physical state (crystalline solid), color (by comparison to platinum-cobalt standards), and absence of visible particulates under controlled lighting. |
