Manufacturing Quality Control of 1,2-BIS(4-PYRIDYL)ETHANE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase chromatography with UV detection at 260 nm based on peak area comparison to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities (e.g., mono-pyridyl analog, dimerization by-products) using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Identifies and quantifies volatile organic solvents (e.g., DMF, methanol, dichloromethane) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine-methanol solvent system. |
| Heavy Metals | ICP-OES | Measures total elemental metal impurities (Pb, Cd, Hg, As, Ni) after acid digestion by optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after separation on anion-exchange column. |
| Sulfate Impurity | Ion Chromatography | Quantifies sulfate ions using suppressed conductivity detection after separation on anion-exchange column. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 750 C and weighing. |
| 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 clarity of crystalline solid against white/black background under controlled lighting. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a saturated aqueous suspension (10 mg/mL) using calibrated pH electrode. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume of freely settled powder using standardized cylinder and weight measurement per ASTM D1895. |
