Manufacturing Quality Control of 4-Bromo-2-methylthiophene
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | GC-FID | Quantifies main component by separation on capillary column and flame ionization detection relative to internal/external standard. |
| Related Substances | GC-MS | Identifies and quantifies impurities via gas chromatographic separation coupled with mass spectral detection. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents using headspace or direct injection GC with FID. |
| Water Content | Karl Fischer Titration | Measures water by coulometric or volumetric titration with iodine generated electrochemically or added stoichiometrically. |
| Heavy Metals | ICP-OES | Determines total heavy metal content (e.g., Pb, Cd, Hg, As) after acid digestion by atomic emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and conductivity detection. |
| Sulfate Impurity | Ion Chromatography | Separates and quantifies sulfate ions using anion-exchange column and conductivity detection. |
| Acid Value | Acid-Base Titration | Measures acidic impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| 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 presence of particulates or phase separation under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic residue remaining after high-temperature ashing of sample in a muffle furnace. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light by chiral compounds in solution using sodium D-line source. |
