Manufacturing Quality Control of 2-Methoxycarbonylsuccinic acid dimethyl 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 polar capillary column. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities using reversed-phase C18 column and gradient elution with UV detection at 210 nm. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated in situ reacts stoichiometrically with water; endpoint detected amperometrically. |
| Residue on Ignition | Gravimetric analysis after high-temperature ashing | Sample ignited at 750-800 C to volatilize organic matter; inorganic residue weighed as sulfate ash. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) after wet digestion | Sample digested with nitric acid and hydrogen peroxide; lead concentration measured by flame AAS at 283.3 nm. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Anion exchange separation followed by suppressed conductivity detection for quantitative chloride determination. |
| Acid Value | Acid-base titration with standardized NaOH solution | Neutralization of free carboxylic acid groups using phenolphthalein indicator and 0.1 M NaOH in isopropanol/water mixture. |
| Color (APHA) | Visual comparison or spectrophotometric measurement | Measurement of yellowness index via absorbance at 430 nm in a 10-mm cell relative to platinum-cobalt standards. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light at 20 C using sodium D-line (589 nm) in a 1-dm cell. |
| Refractive Index | Refractometry | Determination of ratio of speed of light in air versus sample at 20 C using Abbe refractometer. |
| Density | Oscillating U-tube densitometry | Measurement of sample density based on resonant frequency shift of a vibrating U-shaped glass tube filled with sample. |
| Residual Solvents (Methanol, DMF) | Headspace Gas Chromatography (HS-GC) with FID | Thermal equilibration of sample in sealed vial; volatile solvents quantified by GC-FID using internal standard calibration. |
