Industrial Applications of 4-AMINO-3,5-DIIODOPYRIDINE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key intermediate in the synthesis of anticancer agents (e.g., multi-target kinase inhibitors) | Undergoes Suzuki coupling with boronic acid derivatives to construct C–C bonds |
| Pharmaceutical Intermediates | Used in the preparation of radiolabeled diagnostic agents (e.g., ¹²³I/¹³¹I-labeled molecular probes) | Iodine atom participates directly in radioiodination without requiring additional iodine sources |
| Organic Synthesis | Multifunctional heterocyclic building block for constructing iodopyridine derivatives | Amino or iodo sites are modified via nucleophilic substitution, metal-catalyzed cross-coupling, and related reactions |
Manufacturing Quality Control of 4-AMINO-3,5-DIIODOPYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities (e.g., mono-iodinated analogs, dehalogenated by-products) using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., DMF, methanol, dichloromethane) by gas chromatography with flame ionization detection. |
| Heavy Metals | ICP-MS | Multi-element trace metal quantification (e.g., Pb, Cd, Hg, As) after acid digestion, leveraging high sensitivity and isotopic resolution. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration measuring water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based medium. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by high-temperature incineration followed by precise weighing of residual non-volatile matter. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition assessment via controlled heating; sharp melting range indicates crystalline purity and absence of significant eutectic impurities. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using light scattering principles to determine D10, D50, and D90 values relevant to handling and formulation. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction. |
| Specific Optical Rotation | Polarimetry | Measurement of chiral purity (if applicable) or identity confirmation via rotation of plane-polarized light in solution at specified wavelength and temperature. |
| pH (Aqueous Suspension) | pH Meter | Determination of surface acidity/basicity by measuring hydrogen ion activity in a standardized aqueous suspension (e.g., 1% w/v). |
