Manufacturing Quality Control of 2-CHLORO-3-OXO-SUCCINIC ACID DIETHYL 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 suitable capillary column and temperature program. |
| Related Substances (Impurities) | Gas Chromatography (GC) with FID or Mass Spectrometry (GC-MS) | Separation and identification/quantification of structurally related impurities (e.g., diethyl oxalate, chloroacetic acid esters, unreacted glyoxylic acid derivatives) via retention time matching and spectral library comparison. |
| Residual Solvents (e.g., Ethanol, Dichloromethane) | Headspace Gas Chromatography (HS-GC) with FID | Quantification of volatile solvents by equilibrium partitioning into headspace followed by GC separation and detection against calibrated standards. |
| Acid Value | Acid-Base Titration (Potentiometric endpoint detection) | Determination of free acidic impurities (e.g., hydrolyzed carboxylic acids) by titration with standardized potassium hydroxide solution in alcoholic medium. |
| Water Content | Karl Fischer Coulometric Titration | Electrochemical quantification of water based on the stoichiometric iodine generation and reaction with water in anhydrous methanol-based reagent. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element trace metal analysis after microwave-assisted acid digestion, measuring characteristic atomic emission lines. |
| Chloride Ion Content | Ion Chromatography (IC) with Conductivity Detection | Separation of anions on an ion-exchange column and quantitative detection of chloride via suppressed conductivity measurement. |
| Appearance and Color | Visual Inspection and APHA Color Scale Comparison | Assessment of liquid clarity and color intensity by comparison against platinum-cobalt standard solutions under controlled lighting. |
| Density at 20 °C | Oscillating U-tube Densitometry | Precise density measurement based on the resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Refractive Index at 20 °C | Digital Refractometry | Determination of refractive index via critical angle measurement of light passing through the sample at controlled temperature. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Measurement of non-volatile inorganic residue after controlled high-temperature ashing of a weighed sample. |
| Specific Optical Rotation | [α]D²⁰ | Measurement of chiral purity using a polarimeter at sodium D-line wavelength (589 nm), indicating enantiomeric excess if applicable (though compound is achiral; included for identity confirmation per ICH Q5A). |
