Manufacturing Quality Control of 1-(4-ETHYLPHENYL)-2-(4-METHOXYPHENYL)ACETYLENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to calibrated standard. |
| Related Substances | HPLC-DAD | Detects and quantifies impurities by HPLC with diode-array detection, using gradient elution and reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., toluene, THF) via gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration using iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Quantifies trace metals (Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion of sample with sulfuric acid followed by high-temperature ashing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of solid material against standard white background under controlled lighting. |
| Loss on Drying | Thermogravimetric Analysis | Measures mass loss upon heating under nitrogen to remove residual volatiles, per USP <731>. |
| Optical Rotation | Polarimetry | Detects chiral impurities or enantiomeric excess using sodium D-line light through a solution in specified solvent. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder size distribution by measuring angular scattering pattern of laser beam passing through dispersed sample. |
