Industrial Applications of 3-AMINO-6-BROMOPYRAZINE-2-CARBONITRILE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Chemicals | Intermediate in the synthesis of pyrazinamide-class anti-tuberculosis drugs (e.g., pyrazinamide) | Serves as a starting material or key intermediate; the pyrazinamide scaffold is constructed via hydrolysis, amination, and related reactions |
| Pharmaceutical Chemicals | Intermediate in the development of novel antibacterial and antiviral agents | Leverages the compound’s multiple reactive sites—amine, cyano, and bromo groups—for coupling reactions (e.g., Suzuki coupling) or heterocycle modification to build drug candidate libraries |
| Organic Synthesis | Building block for complex pyrazine-containing organic molecules | Functions as a multifunctional pyrazine derivative in nucleophilic substitution, cyclization, and functional group transformation reactions to synthesize biologically active heterocyclic compounds |
Manufacturing Quality Control of 3-AMINO-6-BROMOPYRAZINE-2-CARBONITRILE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification using reversed-phase HPLC with UV detection at ~254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-UV or UPLC-UV | Separation and quantification of impurities (e.g., starting materials, intermediates, degradation products) using gradient HPLC/UPLC with UV detection. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify volatile organic solvents (e.g., DMF, acetone, methanol) based on retention time and peak area calibration. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous medium. |
| Inorganic Residues (Sulfated Ash) | Gravimetric Analysis | Ignition of sample at 600–750 °C followed by sulfuric acid treatment and weighing of residual inorganic ash. |
| Heavy Metals | ICP-MS or ICP-OES | Quantification of elemental impurities (e.g., Pb, Cd, Ni, Cu) after microwave-assisted acid digestion, using mass spectrometry or optical emission detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid-to-liquid phase transition occurs, indicating crystallinity and presence of impurities. |
| Residual Bromine (as Br⁻) | Ion Chromatography (IC) with Conductivity Detection | Separation and quantification of bromide ion in aqueous extract using anion-exchange column and conductivity detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or dispersed powder via light scattering to determine D10, D50, D90 values per USP <429>. |
