Manufacturing Quality Control of N-METHYL-P-TOLUIDINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | Gas Chromatography (GC) with FID | Quantitative separation and detection based on volatility and retention time relative to a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Acid Value | Acid-Base Titration with NaOH | Neutralization of acidic impurities using standardized sodium hydroxide solution and phenolphthalein indicator. |
| Color (APHA) | Visual Comparison or Spectrophotometry (APHA scale) | Comparison of sample color against platinum-cobalt standard solutions at 455 nm wavelength. |
| Density at 20 C | Digital Density Meter | Measurement of mass per unit volume using oscillating U-tube principle calibrated with air and water. |
| Refractive Index at 20 C | Refractometry | Determination of light bending angle at air-sample interface using calibrated Abbe refractometer. |
| Residue on Evaporation | Gravimetric Analysis | Evaporation of a weighed sample under controlled temperature and pressure, followed by weighing of non-volatile residue. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantification of metal ions after acid digestion and atomization, measuring absorption at element-specific wavelengths. |
| Non-Volatile Matter | Gravimetric Analysis | Heating a known mass of sample to constant weight and determining residual solids after volatilization of organic components. |
| Aniline Impurity | Gas Chromatography-Mass Spectrometry (GC-MS) | Separation by GC followed by identification and quantification using characteristic mass fragments and retention time matching. |
| p-Toluidine Impurity | High-Performance Liquid Chromatography (HPLC) | Separation on reversed-phase column with UV detection, comparing peak area against reference standard calibration curve. |
| Odor | Sensory Evaluation | Trained personnel assess presence and intensity of off-odor relative to specification limits under controlled conditions. |
