Manufacturing Quality Control of 4-BROMO-BENZO[B]THIOPHENE-2-CARBOXYLIC ACID METHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-DAD | Detects and quantifies impurities and degradation products via diode-array detection coupled with retention time matching and peak area comparison. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, toluene) using flame ionization detection after headspace or direct injection. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine generation and stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Ni) via inductively coupled plasma mass spectrometry with isotopic detection. |
| 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. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and subsequent weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Optical Rotation | Polarimetry | Measures specific rotation of chiral compounds in solution using plane-polarized light deflection. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles by measuring angular variation in laser light scattering intensity. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated glass electrode. |
