Manufacturing Quality Control of 2-(3-BROMOPHENOXY)TETRAHYDRO-2H-PYRAN
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities by HPLC separation and UV absorbance, using relative response factors or external standards. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., THF, toluene) via gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generation and stoichiometric reaction with water. |
| Heavy Metals | ICP-OES | Measures total elemental impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion by optical emission spectroscopy of excited atoms in plasma. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after anion-exchange column separation. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700-800 C) and precise weighing of the cooled crucible. |
| Optical Rotation | Polarimetry | Determines specific rotation using sodium D-line light through a solution in a defined cell pathlength and concentration. |
| Melting Point | Capillary Melting Point Apparatus | Measures temperature range at which solid transitions to liquid using controlled heating and visual observation of phase change. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of substance against standard references under controlled lighting and against white/black backgrounds. |
| pH of Aqueous Solution | pH Meter | Measures hydrogen ion activity in a saturated aqueous suspension using a calibrated glass electrode system. |
| Bulk Density | Tap Density Analyzer | Determines mass per unit volume after standardized mechanical tapping of a powder sample in a graduated cylinder. |
