Manufacturing Quality Control of Monomethyl maleate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration | Quantifies active ester content via hydrolysis and back-titration with standardized NaOH. |
| Water Content | Karl Fischer Titration | Measures trace water by electrochemical reaction between iodine, sulfur dioxide, and water in methanol medium. |
| Color (APHA) | Visual Comparison or Spectrophotometry | Compares sample color to platinum-cobalt standard solutions using APHA scale. |
| Acid Value | Acid-Base Titration | Determines free carboxylic acid content by titration with KOH in ethanol. |
| Ester Value | Saponification Titration | Measures total ester content via alkaline hydrolysis followed by acid titration of excess base. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration and weighing of residual solids. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies trace metal impurities by measuring absorbance of ground-state atoms in flame or graphite furnace. |
| Chloride Impurity | Potentiometric Titration | Detects chloride ions via titration with silver nitrate using silver indicator electrode. |
| Residual Solvents (e.g., Methanol) | Gas Chromatography (GC) | Separates and quantifies volatile solvents based on retention time and detector response. |
| Melting Point | Capillary Melting Point Determination | Measures temperature range at which solid transitions to liquid using calibrated capillary apparatus. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity by measuring rotation angle of plane-polarized light passing through solution. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of solid particles by measuring angular variation in scattered laser light. |
