Manufacturing Quality Control of 4-Bromophenylacetylene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area against calibrated standard. |
| Related Substances | Gas Chromatography (GC) with FID detection | Detects and quantifies impurities based on relative retention times and response factors. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatile solvents are vaporized in sealed vials and analyzed by GC-FID or GC-MS. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Acidity (as HBr) | Acid-Base Titration with NaOH | Neutralizes acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Heavy Metals | ICP-OES after acid digestion | Quantifies metals (e.g., Pb, Cd, Ni) by atomic emission following microwave-assisted nitric acid digestion. |
| Chloride Content | Ion Chromatography (IC) | Separates and quantifies chloride ions using conductivity detection after aqueous extraction. |
| 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 foreign particles under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing in a muffle furnace. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral impurities (if applicable). |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping of a powder sample in a graduated cylinder. |
