Manufacturing Quality Control of 1-AMINO-2-METHYLNAPHTHALENE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at ~254 nm, comparing peak area against a certified reference standard. |
| Water Content | Karl Fischer Titration | Electrochemical titration based on the reaction of iodine with water in a methanol-based reagent, measuring endpoint potentiometrically. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700–800 °C to combust organic matter; residual inorganic ash is weighed after cooling in a desiccator. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification after acid digestion, using plasma-induced atomic emission at characteristic wavelengths. |
| Chloride Impurity | Ion Chromatography (IC) | Separation of chloride anions on an ion-exchange column with suppressed conductivity detection. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement by observing solid-to-liquid phase change under controlled heating rate (e.g., 1 °C/min). |
| Color (APHA) | Visual Comparison or Spectrophotometric Method | Comparison of sample solution color against APHA platinum-cobalt standards or measurement of absorbance at 430 nm in dilute solution. |
| Organic Volatile Impurities (e.g., solvents) | GC-FID | Separation and quantification of residual solvents using capillary GC with flame ionization detection and internal standard calibration. |
| Related Substances | HPLC-UV (with gradient elution) | Detection and quantification of structurally related impurities (e.g., 1-naphthylamine, 2-methylnaphthalene) using validated gradient HPLC method. |
| Acid Value | Acid-Base Titration | Neutralization of acidic impurities with standardized alcoholic KOH solution using phenolphthalein indicator or potentiometric endpoint detection. |
| Appearance (Clarity & Color) | Visual Inspection | Assessment of clear, pale yellow to amber liquid/ solid appearance in a Nessler tube against white/black background under controlled lighting. |
| Bulk Density | Graduated Cylinder Method | Mass of material freely poured into a calibrated cylinder divided by its settled volume (per ASTM D1895). |
