Manufacturing Quality Control of 4-Iodo-2-nitroaniline
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at ~254 nm, comparing peak area against a certified reference standard. |
| Related Substances (Impurities) | HPLC-UV or UPLC-MS | Separation and detection of structurally related impurities (e.g., isomers, nitro-reduction by-products) via chromatographic resolution and spectral identification/quantification. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., ethanol, toluene, DMF) per ICH Q3C guidelines. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, offering sub-pptr detection limits per ICH Q3D. |
| Moisture Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a controlled anhydrous medium. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement via controlled heating; sharp melting range indicates crystalline purity and absence of eutectic impurities. |
| Residue on Ignition | Gravimetric Analysis | Mass determination of non-volatile inorganic residue after high-temperature ashing (700–800 °C), reflecting inorganic ash content. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and conductivity detection of chloride ions leached from potential chlorinated precursors or reagents. |
| pH of Aqueous Suspension | pH Meter | Measurement of pH in a standardized aqueous suspension (e.g., 1% w/v in water), indicating acidic/basic impurity load or degradation. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample to determine D10, D50, D90 values, relevant for handling, dissolution, and downstream processing. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light, confirming chiral integrity (though compound is achiral, detects chiral contaminants or degradation). |
