Manufacturing Quality Control of 3-(2-CHLORO-PHENYL)-3-OXO-PROPIONIC ACID ETHYL ESTER
| 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 carrier gas. |
| 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 external calibration standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralization of acidic impurities using standardized sodium hydroxide solution with phenolphthalein endpoint detection. |
| Chloride Content | Ion Chromatography (IC) with conductivity detection | Separation of chloride anions on an ion-exchange column and quantification via conductivity response. |
| Heavy Metals (Pb, Cd, Hg, As) | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Element-specific detection after acid digestion and nebulization; provides ultra-trace multi-element quantification. |
| Appearance | Visual Inspection in Standard Light Box | Assessment of physical state, color, and clarity against established visual reference standards under controlled lighting. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as the temperature range at which solid-to-liquid phase change occurs. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light caused by chiral compounds in solution at specified concentration and path length. |
| Residue on Ignition | Gravimetric Analysis after High-Temperature Ashing | Non-volatile inorganic residue mass determined after incineration at 700-800 C and cooling in desiccator. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Hydrogen ion activity measured using calibrated glass electrode and pH meter in a saturated aqueous suspension. |
