Manufacturing Quality Control of DMT-dG(dmf) Phosphoramidite
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-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 by HPLC separation and UV response relative to main peak. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., acetonitrile, dichloromethane) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration with iodine-based reagent reacting stoichiometrically with water. |
| Optical Rotation | [alpha]D Measurement | Determines specific optical rotation using a polarimeter to confirm chiral integrity and enantiomeric purity. |
| Acid Value | Acid-Base Titration | Measures free acidic groups by titration with standardized NaOH solution using phenolphthalein indicator. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions after sample dissolution and filtration using anion-exchange column and conductivity detection. |
| Heavy Metals | ICP-MS | Detects trace metallic impurities (e.g., Pd, Cu, Ni) by inductively coupled plasma mass spectrometry after acid digestion. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature incineration followed by precise weighing of residual residue. |
| Particle Size Distribution | Laser Diffraction | Determines solid particle size distribution in suspension using Mie scattering theory and laser diffraction optics. |
| pH of Aqueous Solution | pH Meter | Measures hydrogen ion activity in a saturated aqueous slurry using calibrated glass electrode pH meter. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms by filtering sample through membrane, culturing on agar media, and counting colony-forming units. |
