Manufacturing Quality Control of 2,5-Dibromopyrazine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~260 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities (e.g., mono-brominated pyrazine, dibromo isomers, unreacted pyrazine) using gradient HPLC-UV. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., DMF, dichloromethane, toluene) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg, As) after acid digestion, offering sub-ppt sensitivity and selectivity. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content based on stoichiometric reaction with water. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid transition temperature using calibrated capillary apparatus per USP <741>. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using suppressed conductivity detection after sample dissolution and filtration. |
| Residue on Ignition | Gravimetric Analysis | Measurement of inorganic ash content after high-temperature incineration (700–800 °C) and weighing of residual residue. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder particle size distribution using Mie scattering theory with automated dispersion. |
| Appearance (Color & Clarity) | Visual Inspection | Comparison of crystalline solid against established reference standards under controlled lighting per USP <191>. |
