Manufacturing Quality Control of 2-MALEIMIDOETHYLAMINE HCL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorbance at specific wavelength using reverse-phase chromatography with calibration against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC separation and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni) using inductively coupled plasma mass spectrometry for ultra-trace detection. |
| Chloride Ion | Ion Chromatography | Separates and quantifies chloride anions using suppressed conductivity detection after anion-exchange chromatography. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Measures hydrogen ion activity in a 1% w/v aqueous solution using calibrated glass electrode. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by high-temperature incineration followed by precise weighing of residual residue. |
| Melting Point | Capillary Melting Point Apparatus | Identifies temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Optical Rotation | Polarimetry | Measures specific rotation of chiral compounds in solution using plane-polarized light and calibrated cell path length. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against defined standards. |
| Bulk Density | Tap Density Measurement | Determines mass per unit volume after standardized tapping of powder in a graduated cylinder. |
