Manufacturing Quality Control of 80741-44-2
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at specified wavelength based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities by comparing retention times and peak areas to qualified reference standards or threshold responses. |
| Residual Solvents | GC-FID | Measures volatile organic solvents using gas chromatography with flame ionization detection and external calibration. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based redox reaction stoichiometry. |
| Heavy Metals | ICP-MS | Quantifies trace metal contaminants (e.g., Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing and precise weighing. |
| Optical Rotation | Polarimetry | Determines specific optical rotation using sodium D-line light to assess chiral purity and enantiomeric excess. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid using calibrated capillary tube method. |
| Appearance | Visual Inspection | Evaluates physical state, color, and clarity of sample against defined visual standards under controlled lighting. |
| pH of Aqueous Solution | pH Meter | Measures hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume of freely settled powder using standardized cylinder and weight measurement. |
