Manufacturing Quality Control of ETHYL 5-CHLOROTHIOPHENE-2-CARBOXYLATE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detection | Quantitative determination based on peak area comparison against a certified reference standard using a calibrated column and detector. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities by retention time and UV absorbance relative to the main peak. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) with FID | Volatile solvent residues are vaporized in sealed vials and quantified via GC-FID using calibration standards. |
| Water Content | Karl Fischer Titration (coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water in the sample. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separation of chloride anions on an ion-exchange column followed by quantitative detection via conductivity measurement. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Multi-element trace metal quantification after acid digestion, based on element-specific mass-to-charge ratios. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities (e.g., free acid) using standardized sodium hydroxide solution and phenolphthalein endpoint. |
| Sulfur Content | Combustion IC (Combustion Ion Chromatography) | Sample combustion converts sulfur to sulfate, which is then separated and quantified by ion chromatography. |
| Appearance | Visual Inspection against Standard Reference | Comparison of sample clarity and color to a defined water-white or pale yellow reference under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using calibrated capillary tube method. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral components in solution at specified concentration and path length. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Non-volatile residue mass determined after incineration at 700-800 C and cooling in a desiccator. |
