| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals / Biotechnology | Key intermediate in the synthesis of nucleic acid therapeutics, including antisense oligonucleotides (ASOs) and siRNA | Used as a protected adenosine monomer in solid-phase synthesis; the 5′-hydroxyl group is protected with a bis(4-methoxyphenyl)(phenyl)methoxy (DMT) group, and the N6 position of the adenine base is protected with a benzoyl group; incorporated into modified oligonucleotide chains via phosphotriester or phosphoramidite chemistry |
| Molecular Biology Research | Synthesis of RNA probes or primers containing 2′-O-methyl modifications | Coupled via standard phosphoramidite chemistry on DNA/RNA synthesizers to construct modified oligonucleotides with enhanced nuclease stability and target-binding affinity |
| Diagnostics Reagent Development | Building block for high-specificity molecular probes | Integrated into fluorescently or biotin-labeled oligonucleotide sequences for target recognition in applications such as in situ hybridization (ISH), quantitative PCR (qPCR), and microarray assays |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound using reverse-phase HPLC with UV detection at specified wavelength based on peak area comparison to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities by comparing retention times and peak areas against reference standards or threshold responses. |
| Residual Solvents | GC-FID | Measures volatile organic solvents using gas chromatography with flame ionization detection, calibrated against standard solutions. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based reagent where water reacts stoichiometrically. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, As) by plasma ionization followed by mass spectrometric detection. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with conductivity detection and external calibration. |
| Residual Palladium | ICP-OES | Measures palladium residue from catalytic hydrogenation using inductively coupled plasma optical emission spectroscopy. |
| Optical Rotation | Polarimetry | Determines specific rotation using sodium D-line light passing through a solution of known concentration and path length. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution by analyzing angular variation in laser light scattering intensity from dispersed sample. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms by filtration, membrane transfer to culture media, incubation, and colony enumeration. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by precise weighing of residual residue. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measures hydrogen ion activity in a defined suspension using calibrated pH electrode and meter. |
