Manufacturing Quality Control of 3-METHYLBENZO[B]THIOPHENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies 3-methylbenzothiophene by retention time and peak area comparison against a certified reference standard. |
| Related Substances | Gas Chromatography-Mass Spectrometry (GC-MS) | Identifies and semi-quantifies impurities based on retention time and characteristic mass fragmentation patterns. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents using equilibrium vapor phase analysis. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between water, iodine, sulfur dioxide, and a base in methanol medium. |
| Acid Value | Acid-Base Titration with NaOH | Determines acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) after acid digestion and plasma excitation. |
| Sulfur Content | Combustion UV Fluorescence Detection | Measures total sulfur by high-temperature combustion to SO2 followed by UV fluorescence quantification. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or foreign matter under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and weighing. |
| Chloride Content | Ion Chromatography (IC) with Conductivity Detection | Separates and quantifies chloride ions using anion-exchange column and conductivity measurement. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral purity (if applicable) or detect optically active impurities. |
