Manufacturing Quality Control of 3,20-Dioxopregna-1,4,9(11),16-tetraen-21-yl acetate
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Structural Confirmation | Nuclear Magnetic Resonance (NMR) | Utilize ¹H-NMR and ¹³C-NMR to analyze chemical shifts and coupling constants of hydrogen and carbon atoms, confirming molecular structural features. |
| Infrared Spectroscopy (IR) | Identify characteristic absorption peaks of functional groups (e.g., carbonyl, hydroxyl, acetate ester), supporting structural elucidation. | |
| Mass Spectrometry (MS) | Determine molecular weight and fragment ions via high-resolution mass spectrometry (HRMS) or LC-MS, verifying molecular formula and structural fragments. | |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Use reversed-phase C18 column with UV detector (e.g., 240–254 nm); determine main component purity by area normalization or external standard method. |
| Thin Layer Chromatography (TLC) | Quickly screen for impurities; compare Rf values between sample and reference standard, used for process control or preliminary purity assessment. | |
| Related Substances / Impurity Testing | HPLC Gradient Elution Method | Optimize mobile phase gradient to separate potential process impurities or degradation products; set impurity limits (e.g., individual impurity ≤0.5%, total impurities ≤1.0%). |
| Residual Solvents | Gas Chromatography (GC), Headspace Injection | Follow ICH Q3C guidelines; use capillary columns (e.g., DB-624) to detect residual solvents such as methanol, ethyl acetate, and acetone, ensuring compliance with specified limits. |
| Drying Loss | Drying Method / Karl Fischer Water Titration | Drying method (constant weight at 105°C) measures volatile substances; Karl Fischer method precisely determines content of crystalline water or adsorbed water. |
| Residue on Ignition | High-Temperature Ashing (700–800°C) | Determine inorganic salts or metal catalyst residues; control total inorganic impurities (typically ≤0.1%). |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Detect residual heavy metals such as lead, arsenic, mercury, and cadmium; comply with pharmacopoeial general chapters (e.g., <20 ppm). |
| Polymorphic Analysis (if applicable) | X-Ray Powder Diffraction (XRPD) | For polymorph-sensitive drugs, confirm the dominant crystal form through characteristic diffraction peaks to ensure batch-to-batch consistency. |
| Melting Point | Capillary Melting Point Apparatus | Determine the melting temperature range as a physical constant to assist in identification and purity evaluation. |
| Specific Rotation | Polarimeter | Measure optical rotation of a solution at a defined concentration under sodium D-line (589 nm), used for identity confirmation and quality consistency control of chiral compounds. |
