Manufacturing Quality Control of N-PHENYLETHYLENEDIAMINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Acid-Base Titration with HCl | Quantifies primary amine content by titration with standardized hydrochloric acid using bromocresol green indicator. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric reaction between water and Karl Fischer reagent (iodine, sulfur dioxide, base, alcohol). |
| Color | Visual Comparison or Spectrophotometry (APHA/Pt-Co Scale) | Measures yellowness intensity by comparing sample color to platinum-cobalt standard solutions at 455 nm. |
| Specific Gravity | Digital Density Meter | Measures density relative to water at specified temperature (e.g., 20/20 degC) using oscillating U-tube principle. |
| Refractive Index | Refractometer | Determines ratio of light velocity in air vs. sample at specified temperature (e.g., 20 degC) via Snell's law. |
| Residue on Ignition | Gravimetric Analysis | Quantifies non-volatile inorganic impurities by high-temperature ashing followed by weighing of residual ash. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Measures total heavy metal content after wet digestion by quantifying absorbance of ground-state atoms at characteristic wavelengths. |
| Chloride Impurity | Potentiometric Titration with AgNO3 | Detects chloride ions by titration with silver nitrate using silver electrode for endpoint detection. |
| Related Substances | Gas Chromatography (GC) with FID | Separates and quantifies organic impurities (e.g., aniline, phenylenediamines, oxidation products) based on volatility and retention time. |
| Melting Point | Capillary Melting Point Apparatus | Determines solid-to-liquid transition temperature range using controlled heating and visual observation. |
| pH of Aqueous Solution | pH Meter | Measures hydrogen ion activity in a saturated aqueous solution using calibrated glass electrode. |
| Appearance | Visual Inspection | Evaluates physical state, clarity, and presence of undissolved particles or phase separation under controlled lighting. |
