Manufacturing Quality Control of (E)-methyl 4-methoxybut-2-enoate
| 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. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling | Separation and quantification of volatile organic solvents by equilibrium partitioning into headspace gas followed by GC-FID analysis. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of free carboxylic acid groups using standardized sodium hydroxide solution with phenolphthalein endpoint detection. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement at 430 nm | Measurement of yellowness intensity by comparing absorbance at 430 nm to APHA color scale standards. |
| Density | Digital Density Meter (Oscillating U-tube principle) | Determination of mass per unit volume via precise measurement of oscillation period of a U-shaped tube filled with sample. |
| Refractive Index | Refractometry (Abbe refractometer) | Measurement of light bending angle at air-sample interface to determine ratio of light velocities, correlated to purity and composition. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal impurities after acid digestion by measuring ground-state atomic absorption at element-specific wavelengths. |
| Chloride Content | Potentiometric Titration with AgNO3 | Precipitation titration where chloride ions react with silver nitrate; endpoint detected by silver ion-selective electrode potential shift. |
| Residue on Ignition | Gravimetric Analysis (Weight Loss on Ignition) | Determination of inorganic ash content by weighing sample before and after high-temperature incineration to constant weight. |
| Optical Rotation | Polarimetry | Measurement of angular rotation of plane-polarized light caused by chiral molecules in solution, indicating enantiomeric composition. |
| Related Substances | High-Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of structurally similar impurities using reversed-phase column and UV absorbance at 210–220 nm. |
