Manufacturing Quality Control of 3-Maleimidopropionic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3B. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine trace water content based on stoichiometric reaction with water. |
| Residue on Ignition | Gravimetric Analysis | Heating sample at 700-800 C to constant weight and measuring non-volatile inorganic residue as percentage of original mass. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, using plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with conductivity detection. |
| pH (1% w/v aqueous solution) | pH Meter Measurement | Direct measurement of hydrogen ion activity in aqueous solution using calibrated glass electrode pH meter. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range over which solid transitions to liquid, using standardized capillary tube method (USP <741>). |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral centers in solution, reported as degrees per dm*g/mL. |
| Solvent Residues (e.g., DMF, acetone) | GC-FID | Quantitative analysis of residual solvents by gas chromatography with flame ionization detection using internal standard calibration. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against defined standards (e.g., white to off-white crystalline powder, free from visible particles). |
| Loss on Drying | Thermogravimetric Analysis | Weight loss measured after drying at 105 C for 2 hours under vacuum or nitrogen, expressed as percentage of initial mass. |
