Manufacturing Quality Control of 2-ETHYNYLBENZALDEHYDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID | Quantifies main component using flame ionization detection after gas chromatographic separation. |
| Related Substances | GC-MS | Identifies and semi-quantifies impurities based on retention time and mass spectral matching. |
| Residual Solvents | GC-FID with headspace | Measures volatile organic solvents by equilibrium headspace sampling and chromatographic separation. |
| Water Content | Karl Fischer Titration | Determines water via coulometric or volumetric titration with iodine-based reagent. |
| Acidity (as HCl) | Acid-Base Titration | Neutralizes acidic impurities with standardized NaOH solution using phenolphthalein indicator. |
| Heavy Metals | ICP-OES | Quantifies Pb, Cd, Hg, As, and other metals by atomic emission after acid digestion. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using conductivity detection after anion exchange. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid under controlled heating. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or phase separation. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to detect chiral impurities or enantiomeric excess. |
| Residue on Ignition | Gravimetric Analysis | Weighs non-volatile inorganic residue remaining after high-temperature ashing. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles in suspension using angular scattering pattern. |
