Manufacturing Quality Control of Di-p-tolylamine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against certified reference standard. |
| Related Substances | HPLC-UV | Identifies and quantifies impurities (e.g., mono-methyl analogs, aniline derivatives) by retention time and peak area relative to main peak. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid, indicating crystallinity and presence of low-melting impurities. |
| Appearance | Visual Inspection | Assesses physical state and color against established reference (white to off-white crystalline powder) under controlled lighting. |
| Water Content | Karl Fischer Titration | Measures trace water via coulometric or volumetric titration using iodine generation in pyridine/methanol-based reagent. |
| Residue on Ignition | Gravimetric Analysis | Determines inorganic ash content by ignition at 700-800 C followed by weighing of residual residue. |
| Heavy Metals | ICP-OES | Quantifies toxic metals (Pb, Cd, Hg, As) after acid digestion by measuring elemental emission intensities at characteristic wavelengths. |
| Chloride Content | Potentiometric Titration | Titrates chloride ions with silver nitrate using silver indicator electrode; endpoint detected by potential inflection. |
| Acid Value | Acid-Base Titration | Measures free acidic impurities by titration with standardized KOH in ethanol, using phenolphthalein indicator. |
| Bulk Density | Graduated Cylinder Method | Determines mass per unit volume (g/mL) of freely settled powder in a calibrated cylinder. |
| Particle Size Distribution | Laser Diffraction | Analyzes size distribution by measuring angular scattering pattern of laser beam passing through dispersed sample. |
| Organic Volatile Impurities | GC-FID | Detects residual solvents (e.g., toluene, xylene) using capillary GC with flame ionization detection and external calibration. |
