Manufacturing Quality Control of 17-Iodoandrosta-5,16-dien-3beta-ol 3-acetate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound using reversed-phase HPLC with UV detection at 240-254 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-DAD | Detects and quantifies structurally related impurities using gradient HPLC with diode-array detection and peak purity assessment. |
| Residual Solvents | GC-FID | Measures residual solvents (e.g., methanol, acetone, ethyl acetate) by headspace GC with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generation and stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies trace heavy metals (Pb, Cd, Hg, As, Ni) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic residue after high-temperature ashing (500-600 C) followed by precise weighing of the ignited residue. |
| Optical Rotation | Polarimetry | Determines specific optical rotation using sodium D-line light to confirm chiral integrity and enantiomeric identity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating crystallinity and absence of significant impurities. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution in dry or wet dispersion mode using Mie scattering theory and intensity distribution inversion. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microbial count and detects specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial methods. |
| pH of Solution | Potentiometric pH Measurement | Determines pH of a standardized suspension (e.g., 1% w/v in water or buffer) using calibrated glass electrode and pH meter. |
| Organic Volatile Impurities (OVI) | GC-MS | Identifies and quantifies unknown or unmonitored volatile organic impurities using gas chromatography coupled with mass spectrometric detection. |
