Manufacturing Quality Control of 2-Thiophenecarboxylicacid,3-fluoro-,methylester(9CI)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities by HPLC separation and UV response relative to the main peak. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, ethyl acetate) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration based on iodine-sulfur dioxide reaction in pyridine-methanol medium. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after combustion in sulfuric acid followed by high-temperature incineration and weighing. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white-light illumination against standard references. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic residue after ignition at 700-800 C in a muffle furnace. |
| pH of Solution | pH Meter | Measures hydrogen ion activity in a 1% w/v aqueous suspension using calibrated glass electrode pH meter. |
