Industrial Applications of 4-CHLORO-3-IODOPYRIDINE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Synthesis of active pharmaceutical ingredients (APIs), including antitumor agents and kinase inhibitors | Used as a key heteroaromatic building block in cross-coupling reactions—such as Suzuki and Heck couplings—to construct C–C bonds |
| Pesticide Development | Development of novel insecticidal and fungicidal molecules | Functionalized via nucleophilic substitution or metal-catalyzed coupling to introduce specific substituents, thereby optimizing biological activity |
| Materials Science | Preparation of electron-transport materials for organic light-emitting diodes (OLEDs) | Employed as a halogenated pyridine structural unit; incorporated into conjugated backbones via lithiation–boronation or direct functional group transformation |
Manufacturing Quality Control of 4-CHLORO-3-IODOPYRIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by 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 impurities (e.g., 4-chloropyridine, 3-iodopyridine, chlorinated/iodinated by-products) relative to main peak using gradient elution. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., DMF, THF, methanol) based on retention time and flame ionization response. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generation in pyridine-methanol medium; measures water via stoichiometric reaction with iodine and sulfur dioxide. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element detection after acid digestion; quantifies metals (Pb, Cd, Hg, As, Cr) by atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation of chloride ions on an anion-exchange column with suppressed conductivity detection; quantified against sodium chloride standard. |
| Iodide Impurity | ICP-OES | Direct determination of total iodine content after sample digestion; distinguishes free iodide from organically bound iodine via total digestion. |
| Melting Point | Capillary Melting Point Apparatus | Determination of solid-to-liquid phase transition temperature range using calibrated capillary tube under controlled heating rate. |
| Loss on Drying | Gravimetric (Thermogravimetric) | Measurement of mass loss after drying at specified temperature (e.g., 105 C) for fixed duration; reflects volatile and moisture content. |
| Residue on Ignition | Sulfated Ash Test | Mass of non-volatile inorganic residue remaining after high-temperature incineration (700-800 C) following sulfuric acid treatment. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity vs. scattering angle to calculate volume-based particle size distribution in dry or wet dispersion. |
| Bulk Density | Tap Density Tester | Measurement of mass per unit volume after standardized mechanical tapping; indicates flowability and packing behavior. |
