| Materials Science | Functional precursor in the preparation of polymeric or nanomaterials | Polymerization, surface modification |
Manufacturing Quality Control of 141846-57-3
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 210-230 nm based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC with UV detection; identification via retention time matching and threshold-based reporting. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., ethyl acetate, toluene, methanol) by headspace GC with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration where iodine reacts stoichiometrically with water in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection and sodium carbonate eluent. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation at 589 nm using a digital polarimeter to confirm stereochemical integrity and enantiomeric purity. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Residue on Ignition | Gravimetric Analysis | Quantifies inorganic ash content by high-temperature incineration (600-800 C) followed by weighing of residual residue. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in dry powder form using Mie theory-based light scattering analysis. |
| Microbial Limits | Membrane Filtration | Detects aerobic microbial count and absence of specified pathogens (e.g., E. coli, S. aureus) using membrane filtration and selective agar culture. |
| pH of Solution | Potentiometric pH Measurement | Determines pH of a defined aqueous suspension (e.g., 1% w/v) using calibrated glass electrode and pH meter. |
