Manufacturing Quality Control of Guanosine-9-17N, N-(2-methyl-1-oxopropyl)-, 2',3'-diacetate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV/HRMS | Separation and identification of structurally related impurities (e.g., deacetylated, hydrolyzed, or isomeric forms) via retention time matching and high-resolution mass confirmation. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., acetone, acetonitrile, ethyl acetate) against calibrated standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element trace metal quantification after acid digestion, using isotopic detection with ultra-low detection limits and matrix-matched calibration. |
| Residual Catalysts (e.g., Pd, Ni) | ICP-OES | Quantification of transition metal residues post-catalytic synthesis by plasma excitation and element-specific emission intensity measurement. |
| Optical Rotation | [α]D | Measurement of specific rotation using a polarimeter at 20 °C with sodium D-line (589 nm) to confirm chiral integrity and enantiomeric identity. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed solid sample via light scattering pattern to determine D10, D50, D90 values per ISO 13320. |
| Microbial Contamination | Membrane Filtration & Culture | Enumeration of aerobic microorganisms and detection of specified pathogens (e.g., E. coli, S. aureus, P. aeruginosa) per USP <61> and <62>. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content after controlled high-temperature incineration (700–800 °C) and precise weighing of residual residue. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measurement of hydrogen ion activity in a standardized aqueous suspension (e.g., 1% w/v) using calibrated pH electrode per USP <791>. |
