Manufacturing Quality Control of 107949-21-3
| 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 relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., toluene, THF, ethanol) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generated electrochemically in a methanol-based reagent. |
| Heavy Metals | ICP-OES | Quantifies elemental impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid phase transition using calibrated capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particles or discoloration against standard white background under controlled lighting. |
| Bulk Density | USP <616> Tap Density Method | Measures mass per unit volume after mechanical tapping of a known powder mass in a graduated cylinder to determine packing behavior. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution of dry powder using Mie scattering theory applied to light diffraction patterns generated by dispersed particles. |
| Optical Rotation | Polarimetry | Measures specific rotation at sodium D-line (589 nm) to confirm chiral integrity and detect racemization or enantiomeric impurities. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C followed by weighing of residual residue after cooling in desiccator. |
