Manufacturing Quality Control of 4-Amino-3-nitrophenol
| 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. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration based on the reaction of iodine with water in a methanol-based solvent system. |
| Residue on Ignition | Gravimetric Analysis | Heating sample to 700–800 °C to combust organic matter; residual inorganic ash is weighed after cooling. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of trace metals after acid digestion, using plasma-induced atomic emission spectroscopy. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride anions using suppressed conductivity detection after aqueous extraction. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition measurement via controlled heating; onset and range indicate purity and identity. |
| Organic Volatile Impurities (e.g., solvents) | GC-FID | Separation and quantification of residual solvents using gas chromatography with flame ionization detection. |
| Related Substances | HPLC-UV (with gradient elution) | Identification and quantification of structurally related impurities (e.g., nitroanilines, azo byproducts) using validated stability-indicating method. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of acidity/basicity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Sulfated Ash | Gravimetric Analysis | Oxidation of organic matrix with sulfuric acid followed by ignition; residue weight reflects inorganic sulfate content. |
| Particle Size Distribution | Laser Diffraction | Analysis of dispersed solid particles in liquid medium using Mie scattering theory to determine size distribution profile. |
| Bulk Density | USP <616> Tap Density Method | Measurement of mass per unit volume before and after standardized mechanical tapping to assess flow and packing behavior. |
| Color (APHA) | Visual Comparison or Spectrophotometric APHA Scale | Quantification of yellowness/brownness by matching to platinum-cobalt standard solutions or measuring absorbance at 455 nm. |
| Water-Soluble Impurities | Conductivity Measurement | Assessment of ionic impurity load via electrical conductivity of aqueous extract (e.g., 10% w/v solution). |
