Manufacturing Quality Control of 3-Bromo-2-iodopyridine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities (e.g., bromopyridine, iodopyridine, dihalo byproducts) using gradient HPLC-UV with suitable column and mobile phase. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., DMF, THF, methanol) using gas chromatography with flame ionization detection and internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration using iodine generated electrochemically or added reagent, based on stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma mass spectrometry for ultratrace sensitivity and multi-element capability. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (500-600 C) and subsequent weighing of the cooled crucible. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating purity and identity via thermal behavior. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles or discoloration under controlled white light against standard references. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity and detect racemization or enantiomeric impurities (if applicable). |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid powder using Mie scattering theory applied to laser light diffraction patterns in dispersed medium. |
| Bulk Density | ASTM D1895 | Measures mass per unit volume of freely settled powder using standardized cylinder and tapping procedure per ASTM method. |
