| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Intermediate in the synthesis of oligonucleotides or modified nucleosides for antiviral or anticancer drug research | Introduced via chemical synthesis or enzymatic reaction to incorporate specific modifications into nucleic acid analog construction |
| Molecular Biology | Preparation of modified probes or primers to enhance nucleic acid hybridization stability or specificity | Used as a protected nucleoside monomer in solid-phase synthesis, incorporated into oligonucleotide chains after deprotection |
| Chemical Reagents | Reference standard or calibrant for HPLC or mass spectrometry method development | Purified material used directly for chromatographic column calibration or as an internal standard in quantitative analysis |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specified wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient reverse-phase HPLC with UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration based on iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column with suppressed conductivity detection. |
| Residual Palladium | ICP-OES | Measures palladium residue after microwave-assisted acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Optical Rotation | [alpha]D Measurement | Determines specific optical rotation using sodium D-line light source to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range of solid-to-liquid phase transition to assess crystallinity and identity. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution in suspension using Mie scattering theory and laser diffraction principles. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms and specified pathogens by filtration, membrane transfer to selective media, and colony enumeration. |
