Manufacturing Quality Control of 2-AMINOTHIOPHENE-3-CARBOXYLIC ACID T-BUTYL ESTER
| 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 relative response factors. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., THF, toluene, methanol) against calibrated standards. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Content | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified via calibration curve. |
| Sulfate Content | Ion Chromatography | Separation and conductivity detection of sulfate ions in aqueous extract; quantified via calibration curve. |
| Residual Palladium | ICP-MS | Ultra-trace quantification of palladium (common catalyst residue) after microwave-assisted acid digestion, using mass spectrometric detection. |
| Optical Rotation | [alpha]D Measurement | Determination of specific optical rotation using a polarimeter at 20 C and sodium D-line (589 nm) to confirm chiral integrity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs under controlled heating. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to calculate volume-based particle size distribution in dry or dispersed state. |
| Bulk Density | ASTM D1895 Method A | Measurement of mass per unit volume for freely settled powder in a standardized graduated cylinder. |
