Manufacturing Quality Control of 2-Amino-3-bromopyrazine
| 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 generated in situ to react stoichiometrically with water; endpoint detected potentiometrically. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using isotopic mass spectrometry for ultra-trace sensitivity. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions after sample dissolution and filtration; quantified against chloride calibration standards. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after controlled high-temperature ashing at 700-800 C, expressed as percentage weight loss. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically during controlled heating; reported as onset and clear point range. |
| Optical Rotation | Polarimetry | Measurement of specific rotation using sodium D-line light (589 nm) in solution; indicates chiral purity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to calculate volume-based particle size distribution in dispersed dry or wet samples. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of pH in a defined suspension (e.g., 1% w/v in water) using a calibrated glass electrode and pH meter. |
| Bulk and Tapped Density | Carr Index Method | Determination of bulk density (loose powder) and tapped density (after standardized mechanical tapping), used to calculate compressibility and flowability. |
