Manufacturing Quality Control of 4-BROMO-5-METHYL-2-THIOPHENECARBOXYLIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., methanol, ethyl acetate, toluene) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction with water. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, based on atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against sodium chloride calibration curve. |
| Sulfated Ash | Gravimetric Analysis | Ignition of sample at 700-800 C followed by weighing of non-volatile inorganic residue after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity and identity via comparison to reference value. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light to assess chiral purity (if applicable) and detect enantiomeric impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to determine volume-based particle size distribution by scattering pattern analysis. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a defined suspension (e.g., 1% w/v in water) using calibrated electrode to assess acidic/basic impurity load. |
| Residual Palladium | ICP-MS | Ultra-trace quantification of palladium (e.g., from catalyst residues) after microwave digestion, using isotope-dilution or external calibration. |
