Manufacturing Quality Control of 7-Hydroxyisoflavone
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies 7-hydroxyisoflavone by UV detection at ~260 nm using a reversed-phase C18 column and external standard calibration. |
| Related Substances | HPLC-DAD | Detects and quantifies structurally related impurities (e.g., isoflavones, degradation products) via diode array detection and peak area comparison. |
| Residual Solvents | GC-FID | Measures residual organic solvents (e.g., methanol, ethyl acetate) using flame ionization detection with headspace sampling. |
| Heavy Metals | ICP-MS | Determines trace levels of toxic elements (Pb, Cd, Hg, As) by mass spectrometric detection after acid digestion. |
| Water Content | Karl Fischer Titration | Determines water content volumetrically using iodine-based redox titration in anhydrous methanol medium. |
| Loss on Drying | Gravimetric Analysis | Measures volatile matter by weight loss after drying at 105 C for 2 hours under controlled atmospheric conditions. |
| Residue on Ignition | Sulfated Ash Test | Quantifies inorganic residue after high-temperature ignition (700–800 C) following sulfuric acid treatment. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles against established reference standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measures optical activity using sodium D-line light to confirm chiral integrity and identity. |
| pH of Solution | Potentiometric pH Measurement | Determines acidity/basicity of a standardized aqueous suspension (e.g., 1% w/v) using calibrated pH electrode. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic mesophilic microorganisms and detects specified pathogens (e.g., E. coli) per Ph. Eur. 2.6.12. |
