Manufacturing Quality Control of 100582-74-9
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 254 nm, based on peak area comparison against certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient HPLC-UV; identification relies on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., toluene, acetone) 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 generated electrochemically in pyridine-free reagent system. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (Pb, Cd, Hg, As, etc.) after acid digestion using inductively coupled plasma mass spectrometry for multi-element detection. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion at 700-750 C followed by weighing of the cooled residue. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of visible particulates or phase separation under controlled white light against standard reference. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light at 20 C using sodium D-line (589 nm) to confirm chiral integrity and batch consistency. |
| Bulk Density | Tap Density Tester | Determines mass per unit volume after standardized mechanical tapping per USP <616> to assess flow and handling properties. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension using Mie scattering theory and validated optical model. |
