Manufacturing Quality Control of 3',4'-DIMETHOXYPHENYL ACETYLENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID | Quantifies main component by separation on capillary column and flame ionization detection. |
| Related Substances | GC-MS | Identifies and quantifies impurities based on retention time and mass spectral matching. |
| Residual Solvents | GC-FID with headspace sampling | Detects volatile organic solvents using equilibrium headspace gas analysis. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration with iodine-based reagent. |
| Heavy Metals | ICP-OES | Determines trace metal concentrations by atomic emission spectroscopy after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Acidity (as HCl) | Acid-Base Titration | Neutralizes acidic impurities with standardized NaOH solution using phenolphthalein indicator. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard reference under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated thermal block. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral impurities or enantiomeric excess. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles suspended in dispersant medium via light scattering pattern. |
