Manufacturing Quality Control of 125700-73-4
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 220 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification via retention time matching and threshold-based reporting. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., DMF, DCM, MeOH) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generation in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni, Pd) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution. |
| Residual Palladium | ICP-MS | Specific quantification of Pd catalyst residue post-coupling synthesis using ICP-MS with palladium-105 or -106 isotopic measurement. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation at 589 nm using sodium D-line to confirm chiral integrity and enantiomeric purity. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Determines acidity/basicity of aqueous solution using calibrated glass electrode and pH meter under controlled temperature. |
| Loss on Drying | Thermogravimetric Analysis (TGA) | Quantifies volatile content and solvent residues by measuring mass loss upon heating to 105 C under nitrogen flow. |
| Particle Size Distribution | Laser Diffraction | Measures dry powder particle size distribution using Mie theory scattering analysis of dispersed aerosolized sample. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtering sample through sterile membrane, then culturing on soybean-casein digest agar under controlled conditions. |
| Endotoxins | Kinetic Chromogenic LAL Assay | Quantifies bacterial endotoxins via Limulus amebocyte lysate reaction producing colorimetric signal proportional to endotoxin concentration. |
