Industrial Applications of 4-IODO-2-NITROPHENOL
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Key intermediate for synthesizing iodinated contrast agents (e.g., iohexol, iopamidol) | Iodine and hydroxyl groups are introduced via nucleophilic substitution or coupling reactions to construct polyhydroxyamide structures |
| Organic Synthesis | Used to prepare other iodinated aromatic compounds | Serves as an aryl iodide source in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Heck) |
| Materials Science | Precursor for synthesizing iodine-containing functional materials | Functional group transformations are employed to build polymers or small molecules with tailored optoelectronic properties |
Manufacturing Quality Control of 4-IODO-2-NITROPHENOL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area 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., nitrophenol isomers, iodobenzenes) relative to main peak using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., methanol, acetone, DMF) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Ni after acid digestion, using plasma excitation and optical emission spectroscopy. |
| Residue on Ignition | Gravimetric Analysis | Determination of inorganic ash content by high-temperature incineration followed by weighing of residual non-volatile matter. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement via controlled heating of a capillary-packed sample, observing solid-to-liquid phase change. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection after aqueous extraction. |
| Iodine Content | Potentiometric Titration with Sodium Thiosulfate | Oxidation of iodide (released by alkaline fusion or hydrolysis) followed by iodometric back-titration. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a saturated aqueous suspension using calibrated glass electrode. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to determine volume-based particle size distribution. |
| Organic Volatile Impurities (Total) | GC-FID | Sum of all detectable volatile organics (excluding solvents) using headspace or direct injection GC with FID detection. |
