Manufacturing Quality Control of 2-NITROTHIOPHENE-4-CARBOXYLIC ACID
| 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 HPLC with UV detection; identification based on retention time matching and threshold limits per ICH Q3B. |
| Residual Solvents | GC-FID | Detection and quantification of volatile organic solvents (e.g., methanol, acetone, DMF) by gas chromatography with flame ionization detection, per ICH Q3C. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppb sensitivity. |
| Chloride Content | Potentiometric Titration | Determination of chloride ions by titration with silver nitrate using a silver indicator electrode; endpoint detected via potential inflection. |
| Sulfated Ash | Gravimetric Analysis | Residue mass after incineration at 700-800 C following sulfuric acid treatment; measures inorganic impurities as sulfate salts. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric determination of water content based on stoichiometric reaction between iodine and water in pyridine/methanol medium. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the temperature range at which solid-to-liquid phase change occurs. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity to determine volume-based particle size distribution in dispersed dry or wet samples. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a defined aqueous suspension (e.g., 1% w/v) using calibrated glass electrode system. |
| Organic Volatile Impurities (OVI) | GC-MS | Identification and quantification of structurally unknown volatile organic impurities using gas chromatography coupled with mass spectrometry. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity and absence of racemization. |
