Industrial Applications of Vilazodone Intermediate
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Intermediate for synthesizing selective 5-HT6 receptor antagonists (e.g., idalopirdine) and potential anti-Alzheimer’s disease candidates | Used as a benzofuran core building block in coupling reactions (e.g., Suzuki or Buchwald–Hartwig cross-coupling); target molecular scaffolds are constructed via multi-step modifications including hydrolysis and amidation |
Manufacturing Quality Control of Vilazodone Intermediate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound by UV absorption at specific wavelength using reverse-phase C18 column and calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient elution and peak area comparison against reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., ethanol, DMF) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction in pyridine-methanol medium. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Ni) after acid digestion by mass spectrometry detection of elemental isotopes. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion at 700-800 C followed by precise weighing of residual ash. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using capillary tube and calibrated thermometer. |
| Optical Rotation | Polarimetry | Measures specific rotation of chiral centers using sodium D-line light through a solution in defined pathlength and concentration. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension by measuring angular variation of scattered laser light. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determines acidity/basicity of saturated aqueous suspension using calibrated glass electrode and pH meter. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms and detects specified pathogens (e.g., E. coli) by filtration, culture on selective media, and colony enumeration. |
