Manufacturing Quality Control of 439948-91-1
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at characteristic wavelength based on peak area comparison to reference standard. |
| Chiral Purity | Chiral HPLC | Measures enantiomeric excess by separating (R)- and (S)-enantiomers on a chiral stationary phase and comparing peak areas. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents using gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration where iodine reacts stoichiometrically with water in anhydrous medium. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Ni) by atomizing and ionizing the sample and measuring elemental mass-to-charge ratios. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column with suppressed conductivity detection. |
| Residual Palladium | ICP-OES | Measures palladium residue from catalytic steps by plasma excitation and optical emission intensity measurement at specific wavelengths. |
| Related Substances | HPLC-UV | Identifies and quantifies structurally related impurities (e.g., hydrolysis/degradation products) using gradient HPLC with UV detection. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid sample against defined standards under controlled lighting conditions. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP/EP guidelines. |
| Loss on Drying | Gravimetric Method | Measures weight loss after drying under specified temperature and vacuum conditions to determine volatile content including residual solvents and moisture. |
