Manufacturing Quality Control of 2-BROMO-5-CHLOROTHIOPHENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantifies main component by retention time and peak area relative to calibration standard. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies impurities based on differential retention and UV absorbance. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Detects volatile organic solvents by equilibrium partitioning into headspace gas phase. |
| Water Content | Karl Fischer Titration | Measures water via stoichiometric reaction between iodine, sulfur dioxide, and water in pyridine/methanol medium. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Quantifies metal impurities by atomic emission intensity after high-temperature plasma atomization. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions by silver nitrate titration monitored via silver electrode potential change. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after controlled high-temperature ashing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against established reference standards under controlled lighting. |
| Acid Value | Acid-Base Titration with NaOH | Measures acidic impurities by titration with standardized sodium hydroxide solution using phenolphthalein indicator. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity or absence of optically active impurities via rotation of plane-polarized light. |
| Bulk Density | Tap Density Measurement | Quantifies mass per unit volume after standardized mechanical tapping of a powder sample in a graduated cylinder. |
