Manufacturing Quality Control of Pyridazine, 3-bromo- (9CI)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantifies 3-bromopyridazine content by retention time and peak area against a certified reference standard. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separates and quantifies structurally related impurities using reversed-phase C18 column and gradient elution. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Detects and quantifies volatile organic solvents (e.g., methanol, acetone, toluene) based on vapor-phase equilibrium and GC separation. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Determines trace water by electrochemical generation of iodine and stoichiometric reaction with water in anhydrous medium. |
| Heavy Metals | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Measures total elemental impurities (e.g., Pb, Cd, Hg, As) after acid digestion and plasma excitation. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Acid Value | Acid-Base Titration with NaOH standard solution | Neutralizes acidic impurities (e.g., HBr, carboxylic acids) using standardized sodium hydroxide and potentiometric endpoint detection. |
| Appearance | Visual Inspection in Clear Glass Container | Assesses physical state, color, and clarity against specified criteria under controlled white-light illumination. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube and controlled heating rate. |
| Residue on Ignition | Gravimetric Analysis (Sulfated Ash) | Measures non-volatile inorganic residue after high-temperature combustion in sulfuric acid medium and weighing. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral impurities or enantiomeric excess using sodium D-line source. |
| Bulk Density | Tap Density Tester (ASTM D1895) | Determines mass per unit volume of freely settled and tapped powder sample using standardized cylinder and tapping mechanism. |
