Manufacturing Quality Control of 2-BROMO-5-AMINO-4-PICOLINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and threshold limits per ICH Q3A. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, DMF) against calibrated standards. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generation in pyridine-free reagent; measures trace water by stoichiometric reaction with Karl Fischer reagent. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and other regulated metals after acid digestion, with detection at sub-ppt levels. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions in aqueous extract; quantified against NaCl calibration curve. |
| Sulfate Impurity | Ion Chromatography | Anion exchange separation followed by suppressed conductivity detection; quantified relative to sulfate standard. |
| Residue on Ignition | Gravimetric Analysis | Mass loss measured after heating sample at 700-800 C to constant weight; reflects inorganic ash content. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or via automated optical detection; correlates with crystalline purity and identity. |
| Appearance | Visual Inspection | Assessment of color and physical state (crystalline powder) against established reference under controlled lighting and white background. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light at 20 C and 589 nm; verifies chiral integrity and absence of racemization. |
| Bulk Density | Tap Density Analyzer | Determined as mass per unit volume after standardized tapping; indicates flowability and consistency for formulation use. |
