| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Organic synthesis intermediate | Used in the synthesis of biologically active compounds, such as intermediates for thyroid hormone analogs or anticancer agents |
| Fine chemicals | Preparation of halogenated aromatic derivatives | Applied as iodinated aromatic esters in coupling reactions (e.g., Suzuki, Heck) to construct complex molecular frameworks |
| Materials science | Functional material precursor | Employed to prepare aromatic backbone units in specialized optoelectronic materials or liquid crystal molecules |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, dichloromethane) by gas chromatography with flame ionization detection against calibrated standards. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration based on iodine consumption in a pyridine-methanol solvent system. |
| Heavy Metals | ICP-MS | Quantifies trace metal impurities (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Iodine Content | Potentiometric Titration | Measures total iodine by oxidation to iodate followed by iodometric back-titration with sodium thiosulfate using starch indicator. |
| Acid Value | Acid-Base Titration | Determines free carboxylic acid content by titration with standardized NaOH solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Measures inorganic ash content by high-temperature incineration and weighing of residual residue. |
| Melting Point | Capillary Melting Point Apparatus | Determines purity-related thermal transition temperature using controlled heating and visual observation of solid-to-liquid phase change. |
| Appearance | Visual Inspection | Assesses physical state, color, and clarity of sample against defined specifications under controlled lighting conditions. |
| Particle Size Distribution | Laser Diffraction | Measures particle size distribution in dry powder form using Mie scattering theory applied to laser diffraction patterns. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity (if applicable) by measuring rotation of plane-polarized light in solution at specified concentration and wavelength. |
