Manufacturing Quality Control of 4-AMINO-5-BROMO-3-METHYLPYRIDINE
| 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 relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common solvents (e.g., methanol, acetone, DMF) based on calibrated external standards. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generation in pyridine-free reagent; measures water by stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals | ICP-MS | Multi-element quantification of Pb, Cd, Hg, As, and others after acid digestion, using isotopic detection with high sensitivity and low detection limits. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride anion using suppressed conductivity detection with carbonate eluent and standard calibration. |
| Sulfate Impurity | Ion Chromatography | Determination of sulfate anion via ion exchange chromatography with conductivity detection and external calibration. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled ashing at 700-800 C, expressed as percentage of initial sample mass. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection by observing solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light passing through a solution, indicating chiral purity and identity. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution in suspension. |
| Bulk Density | USP <616> Tap Density Test | Determination of mass per unit volume before and after mechanical tapping to assess flowability and packing behavior. |
