Manufacturing Quality Control of Trans-4-(Maleimidomethyl)cyclohexanecarboxylic Acid-NHS
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, relative to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification based on retention time comparison and peak area normalization. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., acetone, ethyl acetate) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-free reagents. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C and subsequent weighing. |
| Optical Rotation | Polarimetry | Determines specific optical rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range of solid-to-liquid transition using calibrated capillary method per USP <741>. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines hydrogen ion activity in a 1% w/v aqueous suspension using standardized pH electrode and buffer calibration. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size via Mie scattering theory using a laser diffraction particle size analyzer. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms and detects specified pathogens (e.g., E. coli, S. aureus) per USP <61> and <62>. |
