Industrial Applications of 122111-11-9
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Key intermediate in the synthesis of the anticancer drug gemcitabine | Used as a glycosyl donor in the construction of nucleoside-based drugs via multi-step organic synthesis under sterile conditions, followed by hydrolysis and deprotection to produce the final product |
Manufacturing Quality Control of 122111-11-9
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state, and presence of agglomeration or visible particulates under natural light or standard illumination. |
| Identification | Infrared Spectroscopy (IR) | Determine the sample's infrared absorption spectrum and compare it with a reference standard or reference spectrum to confirm the presence of characteristic molecular functional groups. |
| Nuclear Magnetic Resonance Spectroscopy (¹H NMR, ¹⁹F NMR) | Analyze the chemical environment of hydrogen and fluorine atoms using proton and fluorine NMR spectra to verify structural consistency. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (e.g., at 254 nm) to determine the main component content via external standard or area normalization methods. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate impurities using gradient or isocratic elution; detect and quantify individual impurity peaks to evaluate purity and assess impurity limits. |
| Residual Solvents | Gas Chromatography (GC) | According to ICH Q3C guidelines, detect residual levels of organic solvents used during manufacturing (e.g., methanol, ethanol, ethyl acetate). |
| Water Content | Karl Fischer Titration | Precisely measure water content in the sample using coulometric or volumetric methods, suitable for controlling moisture-sensitive intermediates. |
| Melting Point | Melting Point Instrument | Use an automatic melting point instrument to determine the initial and final melting temperatures of the compound, aiding in identification and purity assessment. |
| Specific Optical Rotation | Polarimeter | Measure the optical rotation of a solution at a specified wavelength (e.g., sodium D line, 589.3 nm) and temperature, and calculate the specific optical rotation to evaluate optical purity. |
| Particle Size Distribution (if applicable) | Laser Diffraction Analysis (LDI) | For solid active pharmaceutical ingredients (APIs) or intermediates, measure particle size distribution to control reactivity or downstream processing performance if required. |
| Thermal Stability | Differential Scanning Calorimetry (DSC) | Analyze the sample's endothermic or exothermic behavior during heating to determine melting, decomposition, or polymorphic transition characteristics. |
| Polymorph Analysis (if applicable) | X-ray Powder Diffraction (XRPD) | Used to confirm the presence of specific polymorphic forms, particularly when polymorphism may affect stability. |
