Manufacturing Quality Control of 79276-23-6
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification by retention time matching and threshold-based reporting. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., acetone, methanol, ethyl acetate) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration with iodine-based reagent, based on stoichiometric reaction with water. |
| Optical Rotation | [alpha]D Measurement | Measures specific optical rotation using sodium D-line light to confirm chiral integrity and enantiomeric purity of the S-configured center. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Ni, Cu) by inductively coupled plasma mass spectrometry after acid digestion. |
| Residual Palladium | ICP-MS | Specific quantification of palladium catalyst residues using ICP-MS following microwave-assisted acid digestion. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and gravimetric weighing. |
| Particle Size Distribution | Laser Diffraction | Determines dry powder particle size distribution by measuring angular scattering pattern of laser light passed through dispersed sample. |
| Microbial Limits | Membrane Filtration | Detects aerobic microorganisms and specified pathogens using membrane filtration followed by incubation on selective agar media. |
| pH of Aqueous Suspension | Potentiometric Titration | Measures pH of a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode and pH meter. |
