Manufacturing Quality Control of 863453-61-6
| Test Item | Common Test Methods | Method Summary |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with reference spectra to confirm functional groups and structural characteristics. |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Use NMR technology to analyze chemical shifts, coupling constants, and other properties of hydrogen atoms to verify molecular structure and stereochemistry. | |
| Mass Spectrometry (MS) | Determine molecular ion peaks and fragment ions to confirm molecular weight and structural information. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase column with a UV detector to quantify the main component, typically employing external standard or area normalization methods. |
| Enantiomeric Purity (Optical Purity) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Use chiral stationary phase columns to separate enantiomers and determine the enantiomeric excess (e.e.) of the (R)-isomer. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection to detect residual organic solvents (e.g., dichloromethane, methanol) from synthesis or purification processes. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Loss on Drying Method | Heat the sample at a specified temperature and measure mass loss to evaluate moisture and volatile content. |
| Residue on Ignition / Inorganic Impurities | Residue on Ignition Test | Weigh inorganic residue after high-temperature incineration to assess residual inorganic salts or metal catalysts. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use gradient elution to separate and quantify process impurities, degradation products, and other related substances. |
| Specific Optical Rotation | Polarimetry | Measure the optical rotation of a sample solution at a specified wavelength (typically sodium D-line, 589 nm) and temperature, then calculate specific optical rotation to confirm optical activity and purity. |
