| Materials Science | Monomer for optically active polymers | Employed in ring-opening polymerization |
| Organic Synthesis | Chiral ligand or catalyst precursor | Utilized in transition metal-catalyzed asymmetric catalytic reactions |
Manufacturing Quality Control of (4R,5S)-(+)-4-METHYL-5-PHENYL-2-OXAZOLIDINONE
| Test Item | Commonly Used Testing Method | Method Overview |
|---|---|---|
| Chemical Purity | High-Performance Liquid Chromatography (HPLC) | Reverse-phase C18 column is used, with methanol/water or acetonitrile/water as the mobile phase. The UV detector (e.g., 210–254 nm) is used to detect the main peak area, based on which the purity of the target compound is calculated. |
| Enantiomeric Purity (Optical Purity) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | A chiral stationary phase column (e.g., Chiralpak AD-H, OD-H) is used to separate enantiomers under specific mobile phase conditions. Enantiomeric excess (e.e.) is calculated based on peak areas. |
| Melting Point | Melting Point Determination | Determination of the melting temperature range using a capillary melting point apparatus or digital melting point apparatus according to pharmacopoeia methods, used to assess purity and crystal form consistency. |
| Specific Optical Rotation | Polarimetry | The specific optical rotation of the sample solution is measured using a polarimeter at a specified wavelength (usually the sodium D line, 589 nm) and temperature to verify its optical activity and configurational consistency. |
| Water Content | Karl Fischer Titration | Karl Fischer reagent is used to quantitatively react with water in the sample. The water content is determined by coulometric or volumetric methods to ensure the product meets drying requirements. |
| Residual Solvents | Gas Chromatography (GC) | Headspace or direct injection GC with FID detector is used. Residual organic solvents from synthesis or purification processes (e.g., methanol, ethanol, dichloromethane) are detected according to pharmacopoeia or ICH guidelines. |
| Structure Confirmation | Nuclear Magnetic Resonance (NMR), Infrared Spectroscopy (IR), Mass Spectrometry (MS) | ¹H NMR and ¹³C NMR are used to confirm molecular structure and stereochemistry; IR is used to identify functional groups (e.g., oxazolidinone ring); MS (ESI or EI) is used to confirm molecular weight and fragment information. |
| Appearance and Color | Visual Inspection | Sample color and physical form (e.g., white to off-white crystalline powder) are observed under standard lighting conditions to determine compliance with quality specifications. |
