Manufacturing Quality Control of 2-AMINO-5-METHYL-THIOPHENE-3-CARBOXYLIC ACID METHYL ESTER
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Identifies and quantifies impurities by retention time and peak area relative to main peak using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., methanol, toluene) via headspace GC with flame ionization detection. |
| Moisture Content | Karl Fischer Titration | Determines water content by coulometric or volumetric titration using iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-OES | Measures total elemental impurities (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Chloride Content | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after separation on anion-exchange column. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion with sulfuric acid treatment and high-temperature ignition. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube method per USP <741>. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light caused by chiral centers in solution, indicating enantiomeric purity. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic residue after ignition at 700-800 C without sulfuric acid pretreatment. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using angular scattering pattern of laser beam. |
