Manufacturing Quality Control of 11a-Hydroxy-16,17a-epoxyprogesterone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specified wavelength using reverse-phase C18 column and calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities via gradient elution and peak area comparison against reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone) using flame ionization detection after headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) at sub-ppb levels using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled incineration of sample with sulfuric acid. |
| Optical Rotation | Polarimetry | Determines specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Identifies purity and identity by measuring temperature range at which solid transitions to liquid under standardized heating rate. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension using angular scattering pattern of laser beam. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms and detects specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial guidelines. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measures hydrogen ion activity in a defined suspension using calibrated glass electrode and reference electrode. |
