Manufacturing Quality Control of 5-NITRO-BENZO[B]THIOPHENE-2-CARBOXYLIC ACID METHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area 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 elution and UV detection; identification via retention time matching with reference standards. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Volumetric titration using iodine-based reagent where water reacts stoichiometrically with iodine, sulfur dioxide, and base in methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantification after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of anions on an ion-exchange column followed by suppressed conductivity detection for quantitative chloride determination. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C to oxidize organic matter, followed by dissolution of inorganic residue and weighing of residual sulfate salts. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range over which solid-to-liquid phase change occurs under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized white light and against specified reference standards. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity and identity. |
| Residual Catalyst (Pd) | ICP-MS | Ultra-trace quantification of palladium after microwave-assisted acid digestion using mass spectrometric detection of isotope 105Pd. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns from suspended particles to determine volume-based size distribution. |
