Manufacturing Quality Control of 2-Nitrodiphenylamine
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration where iodine reacts stoichiometrically with water in a methanol-based solvent system. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, indicating purity and identity. |
| Color (APHA) | Visual Comparison or Spectrophotometric Measurement | Comparison of sample solution color intensity against APHA platinum-cobalt standards using transmitted light at 430 nm. |
| Residue on Ignition | Gravimetric Analysis | Measurement of non-volatile inorganic residue after high-temperature ashing at 700-800 C. |
| Heavy Metals (as Pb) | Colorimetric Sulfide Precipitation | Formation of colored metal sulfide complexes in acidic medium, compared visually or spectrophotometrically against lead standard. |
| Chlorinated Impurities (e.g., o-chloronitrobenzene) | GC-FID | Separation by gas chromatography followed by flame ionization detection; quantified using relative response factors. |
| Nitro Group Content | Reduction-Titration (Zinc/Acetic Acid + KMnO4) | Reduction of nitro groups to aromatic amines, followed by oxidative back-titration of excess reducing agent. |
| Acid-Insoluble Matter | Filtration and Gravimetry | Insoluble residue collected on a pre-weighed filter, dried, and weighed after washing with dilute acid. |
| Sulfated Ash | Gravimetric Analysis | Residue weight after incineration with sulfuric acid pretreatment to convert metals to sulfates. |
| Organic Volatile Impurities | Headspace GC-MS | Extraction of volatiles into headspace followed by separation and identification/quantification via mass spectrometry. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to determine size distribution by volume. |
