Manufacturing Quality Control of 4-AMINO-P-TERPHENYL
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination based on peak area comparison with a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities (e.g., diamino derivatives, residual halides) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., toluene, DMF) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine generated electrochemically to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, based on atomic emission intensity at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions eluted from an anion-exchange column after sample dissolution and filtration. |
| Sulfate Impurity | Ion Chromatography | Separation and conductivity detection of sulfate ions using an anion-exchange column and suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating crystallinity and presence of impurities. |
| Appearance | Visual Inspection | Assessment of physical state, color, and absence of visible particulates or discoloration against a white background under controlled lighting. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue remaining after high-temperature ashing (700-800 C) and cooling in a desiccator. |
| Bulk Density | ASTM D1895 | Determination of mass per unit volume of freely settled powder using a calibrated cylinder and standardized tapping procedure. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity as a function of angle to calculate volume-based particle size distribution in a dispersed slurry. |
