Industrial Applications of 5-Amino-2,4,6- triiodisophthaloyl acid dichloride
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Intermediate for non-ionic contrast agents | Serves as a key monomeric raw material; reacts via condensation with side chains (e.g., acetylated amino acid side chains) to synthesize non-ionic X-ray CT contrast agents such as iohexol, iopamidol, and ioversol. |
| Chemical Synthesis | Monomer for functional polymeric materials | Leverages the high reactivity of its amino and acid chloride groups in step-growth polymerization or interfacial polycondensation to produce iodine-containing polyester or polyamide materials for X-ray shielding or biomedical applications. |
| Chemical Synthesis | Organic synthesis reagent | Acts as an acylating agent in organic synthesis reactions, introducing an iodobenzoyl group onto target molecules via its highly reactive acid chloride group to modify molecular polarity or density through incorporation of high-atomic-number iodine. |
| Research | Contrast agent structural modification studies | Used in pharmaceutical R&D laboratories to synthesize novel contrast agent derivatives; structural modifications at the amino or acid chloride terminus optimize osmolality, viscosity, and biocompatibility. |
Manufacturing Quality Control of 5-Amino-2,4,6- triiodisophthaloyl acid dichloride
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, calibrated against certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and peak area normalization. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., acetone, dichloromethane) against external standards. |
| Moisture Content | Karl Fischer Titration | Volumetric titration with iodine-based reagent to determine water content via stoichiometric reaction with pyridine/methanol buffer. |
| Heavy Metals | ICP-OES | Multi-element quantification of Pb, Cd, Hg, As, and Cr after acid digestion, using plasma emission spectroscopy with internal standard correction. |
| Chloride Content | Potentiometric Titration | Titration with standardized silver nitrate solution using silver indicator electrode to detect endpoint based on AgCl precipitation potential shift. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized NaOH solution using phenolphthalein indicator or potentiometric endpoint detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid-to-liquid phase transition occurs under controlled heating rate per USP <741>. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry powder dispersion using laser scattering principles to calculate D10, D50, D90 values per ISO 13320. |
| Bulk Density | ASTM D1895 Method A | Measurement of mass per unit volume for freely settled powder in a graduated cylinder under standardized tapping conditions. |
| Residue on Ignition | Gravimetric Analysis | Weighing of non-volatile residue remaining after high-temperature ashing (600-800 C) of sample in platinum crucible. |
| Microbial Limits | Membrane Filtration | Quantitative recovery and enumeration of aerobic microorganisms from dissolved sample using sterile membrane filtration and TSA agar incubation. |
