Manufacturing Quality Control of 2-Bromo-5-chloropyridine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID detector | Quantitative determination based on peak area comparison against a certified reference standard using a non-polar capillary column. |
| Related Substances | High Performance Liquid Chromatography (HPLC) with UV detection | Separation and quantification of impurities using reversed-phase C18 column and gradient elution with UV detection at 254 nm. |
| Residual Solvents | Gas Chromatography (GC) with Headspace sampling and FID | Headspace GC analysis to detect and quantify volatile organic solvents (e.g., dichloromethane, methanol) based on calibrated external standards. |
| Water Content | Karl Fischer Titration (Coulometric mode) | Electrochemical titration where iodine generated coulometrically reacts stoichiometrically with water in the sample. |
| Heavy Metals (as Pb) | Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | Multi-element quantitative analysis after acid digestion; detection based on element-specific atomic emission lines. |
| Chloride Impurity | Ion Chromatography (IC) with conductivity detection | Separation of anions on an ion-exchange column and quantification via suppressed conductivity detection. |
| Residue on Ignition | Gravimetric analysis (Weight loss on ignition) | Measurement of non-volatile inorganic residue after incineration at 700-800 C in a muffle furnace. |
| Melting Point | Capillary melting point apparatus | Determination of temperature range at which solid transitions to liquid, using calibrated digital melting point instrument. |
| Appearance | Visual inspection under controlled lighting | Assessment of physical state, color, and clarity against defined standards (e.g., white to off-white crystalline powder). |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at specified concentration and path length. |
| pH of Aqueous Suspension | pH meter with combination electrode | Measurement of hydrogen ion activity in a saturated aqueous suspension prepared per USP general chapter <791>. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Determination of size distribution based on angular variation in intensity of laser light scattered by particles in suspension or air stream. |
