Manufacturing Quality Control of HYDROXYETHYL BETA-CYCLODEXTRIN
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 200-210 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of structurally similar impurities (e.g., unreacted cyclodextrin, hydrolysis products) using gradient HPLC-UV. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Mass loss measured after drying at 105 C for 3 hours under controlled humidity; reflects volatile content including residual solvents and water. |
| Residual Solvents | GC-FID | Detection and quantification of common process solvents (e.g., methanol, ethanol, acetone) using gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, As, Hg) by inductively coupled plasma mass spectrometry after acid digestion. |
| Sulfated Ash | Gravimetric (Ignition) | Residue mass after incineration at 500-600 C; indicates inorganic impurities and catalyst residues. |
| pH (1% w/v solution) | Potentiometric Titration | Measurement of hydrogen ion activity in aqueous solution using calibrated pH electrode; reflects acidic/basic degradation products. |
| Optical Rotation | Polarimetry | Determination of specific rotation using sodium D-line light; confirms chiral integrity and identity based on characteristic旋光值. |
| Water Content | Karl Fischer Titration | Coulometric or volumetric titration with iodine-based reagent to quantify total water content via stoichiometric reaction. |
| Microbial Limits | Membrane Filtration | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus) per pharmacopoeial methods. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed powder using light scattering to determine D10, D50, D90 values relevant to dissolution and handling. |
| Identity Confirmation | FTIR Spectroscopy | Comparison of sample infrared absorption spectrum with reference standard to verify functional groups (e.g., OH, glycosidic bonds). |
