Manufacturing Quality Control of 943757-71-9
| 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, comparing peak area to calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities by gradient HPLC separation and UV response relative to main peak. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) using gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction in pyridine/methanol medium. |
| Optical Rotation | [alpha]D Measurement | Measures specific rotation at 589 nm using a polarimeter to confirm chiral integrity and enantiomeric excess. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry. |
| 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 (700-800 C) incineration and weighing. |
| pH of Aqueous Solution | Potentiometric pH Measurement | Determines pH of a 1% w/v solution in water using calibrated glass electrode and pH meter. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity against standard references under controlled lighting and white background. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder using standardized graduated cylinder and balance. |
