Manufacturing Quality Control of THIOPHEN-3-AMINE HYDROCHLORIDE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC with UV detection | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV absorbance at ~254 nm. |
| Loss on Drying (LOD) | Gravimetric thermogravimetry | Measurement of mass loss after drying under controlled temperature and vacuum to determine volatile content, including residual solvents and moisture. |
| Residual Solvents (e.g., ethanol, acetone) | Gas Chromatography (GC-FID) | Separation and quantification of volatile organic solvents using capillary GC column and flame ionization detection relative to internal standard calibration. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element trace metal quantification via plasma ionization and mass spectrometric detection with isotopic resolution and low detection limits. |
| Chloride Impurity (Cl⁻) | Potentiometric titration with AgNO₃ | Titration using silver nitrate solution with silver/silver chloride electrode; endpoint detected by abrupt potential change due to AgCl precipitation. |
| Related Substances | HPLC with diode-array detection (DAD) | Identification and quantification of structurally related impurities (e.g., 3-nitrothiophene, 3-acetamidothiophene) using gradient elution and spectral library matching. |
| pH of Aqueous Solution (1% w/v) | pH potentiometry | Measurement of hydrogen ion activity in aqueous suspension using calibrated pH electrode and standardized buffer solutions. |
| Melting Point | Capillary melting point apparatus | Determination of solid-to-liquid phase transition temperature range using controlled heating and visual observation of meniscus movement. |
| Sulfate (SO₄²⁻) | Barium sulfate gravimetric method | Precipitation of sulfate as insoluble BaSO₄ under acidic conditions, followed by filtration, drying, and weighing of the pure precipitate. |
| Water Content (Karl Fischer) | Coulometric Karl Fischer titration | Electrochemical generation of iodine to react stoichiometrically with water; quantification based on total charge required for complete reaction. |
| Specific Optical Rotation | [α]D | Measurement of plane-polarized light rotation angle using sodium D-line (589 nm) in solution, indicating chiral purity and identity confirmation. |
| Particle Size Distribution | Laser diffraction analysis | Determination of size distribution by analyzing angular variation in laser light scattering intensity from dispersed particles in liquid medium. |
| Microbial Limits | Membrane filtration followed by agar culture | Enumeration of aerobic mesophilic bacteria and fungi using selective media and incubation per pharmacopoeial guidelines (e.g., USP <61>). |
