Manufacturing Quality Control of DMT-dG(ib) Phosphoramidite
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 260 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification by retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., acetonitrile, dichloromethane) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based redox reaction in anhydrous methanol/pyridine medium. |
| Acid Value | Acid-Base Titration | Measures free acidic groups (e.g., phosphonic acid) by titration with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Phosphorus Content | ICP-OES | Quantifies total phosphorus after microwave-assisted acid digestion by measuring atomic emission intensity at characteristic wavelength (e.g., 213.6 nm). |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Detects trace heavy metals following sample digestion and dilution; uses mass spectrometry for element-specific detection at sub-ppt levels. |
| Optical Rotation | [alpha]D Measurement | Determines specific optical rotation using sodium D-line light (589 nm) to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities. |
| Residue on Ignition | Gravimetric Analysis | Quantifies inorganic ash content after high-temperature (700-800 C) incineration and weighing of residual non-volatile material. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder size distribution by measuring angular variation in laser light scattering intensity. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to culture media, and colony enumeration after incubation. |
