Manufacturing Quality Control of 2-(4-Aminophenyl)-1H-benzimidazol-5-amine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies APBIA peak area against a calibrated standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV | Separates and quantifies structurally related impurities (e.g., mono-amino intermediates, oxidation products) using gradient elution and UV detection. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., DMF, toluene, methanol) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration based on the stoichiometric reaction of iodine with water in pyridine/methanol medium. |
| Heavy Metals | ICP-OES | Determines total elemental impurities (e.g., Pb, Cd, Ni, Fe) after acid digestion by measuring atomic emission intensities at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Sulfate Impurity | Ion Chromatography | Quantifies sulfate ions via suppressed conductivity detection following sample dissolution and dilution in deionized water. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (700–800 C) and weighing of the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid APBIA transitions to liquid, indicating crystallinity and absence of significant eutectic impurities. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles or discoloration under controlled white light against established reference standards. |
| Bulk Density | USP <616> Tap Density Method | Measures mass per unit volume after standardized tapping; indicates flowability and packing behavior for downstream processing. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular variation in laser light scattering from dispersed particles in air or liquid medium. |
