Industrial Applications of 1911578-98-7
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Used as a prodrug or intermediate in antiviral drug development, particularly nucleotide analog prodrugs targeting hepatitis C virus (HCV) | Applied as a key chiral phosphonylation reagent in the synthesis of sofosbuvir and its derivatives, enabling intracellular targeted release of active metabolites via ester linkages and phosphonyl functionality |
Manufacturing Quality Control of 1911578-98-7
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210-254 nm, comparing peak area to a qualified reference standard. |
| Chiral Purity | Chiral HPLC | Measures enantiomeric excess by separating (S)- and (R)-enantiomers on a chiral stationary phase with UV detection. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., ethyl acetate, heptane) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni, As) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Residual Phosphorus Reagents | 31P NMR Spectroscopy | Identifies and semi-quantifies phosphorous-containing impurities (e.g., phosphonic acids, phosphorochloridates) by chemical shift analysis. |
| Acid Value | Acid-Base Titration | Measures free acidic groups by titration with standardized NaOH solution using phenolphthalein or potentiometric endpoint detection. |
| Optical Rotation | [a]D Measurement | Determines specific optical rotation at 589 nm using a polarimeter to confirm chiral integrity and batch consistency. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample to determine size distribution based on Mie scattering theory. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual or automated detection. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms by filtration, membrane transfer to culture media, and colony enumeration after incubation. |
