Manufacturing Quality Control of 4-n-Propoxyphenylacetylene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component peak area relative to calibration standard using flame ionization detection. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and mass spectral fragmentation patterns. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Measures volatile organic solvents by equilibrium partitioning into headspace followed by GC separation. |
| Water Content | Karl Fischer Titration (Coulometric) | Determines water via electrochemical generation of iodine reacting stoichiometrically with water in anhydrous medium. |
| Acidity (as HCl) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution with potentiometric endpoint detection. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) | Quantifies trace metals after acid digestion by measuring element-specific atomic emission intensities. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid phase under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of particulates or phase separation against established reference standards. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral compounds in solution at specified concentration and path length. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue after high-temperature ashing and weighing of the crucible residue. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume of powder after standardized mechanical tapping according to USP <616>. |
