Manufacturing Quality Control of 16a,17a-Epoxyprogesterone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies 16,17-epoxyprogesterone by separation on a reversed-phase column and UV detection at ~240 nm. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient elution and UV absorbance. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., acetone, methanol) via gas chromatographic separation and flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration with iodine-based reagent. |
| Heavy Metals | ICP-MS | Quantifies trace heavy metals (e.g., Pb, Cd, Hg) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after combustion with sulfuric acid and high-temperature incineration. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light to confirm chiral integrity and identity. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition to verify crystalline identity and purity. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size by measuring angular variation in laser light scattering. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration. |
| Residual Catalyst (e.g., Pd) | ICP-OES | Quantifies palladium and other metal catalysts after microwave-assisted digestion using inductively coupled plasma optical emission spectroscopy. |
