Manufacturing Quality Control of 2,2'-Cyclouridine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 260 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time relative to reference standards or threshold limits. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, acetone, ethyl acetate) against calibration curves. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine-based reagent to determine trace water content based on stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for ultra-trace sensitivity. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified via external calibration with NaCl standard. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 500-600 C followed by weighing of non-volatile inorganic residue as sulfate ash. |
| Optical Rotation | [alpha]D Measurement | Measurement of specific rotation using sodium D-line light source to confirm chiral integrity and enantiomeric purity. |
| pH of Solution | Potentiometric pH Measurement | Determination of pH in a defined aqueous solution (e.g., 1% w/v) using calibrated glass electrode and pH meter. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser diffraction to determine volume-based particle size distribution (D10, D50, D90). |
| Microbial Contamination | Membrane Filtration | Quantitative enumeration of aerobic microorganisms and absence of specified pathogens (e.g., E. coli, S. aureus) per pharmacopeial guidelines. |
| Residual Catalyst (Pd) | ICP-OES | Quantification of palladium residue after microwave-assisted digestion using inductively coupled plasma optical emission spectrometry. |
