Manufacturing Quality Control of 4-NITRO-2-SULFOANILINE
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state, and presence of visible impurities. Pure product is typically a yellow or light brown crystalline powder. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (detection wavelength approximately 260–370 nm), and quantify the main component using external or internal standard methods. |
| Purity Analysis | High-Performance Liquid Chromatography (HPLC) | Calculate purity based on the ratio of the main peak area to the total peak area in the HPLC chromatogram; assess the number and quantity of organic impurities. |
| Moisture Content | Karl Fischer Titration | Quantitatively determine moisture content in the sample using Karl Fischer reagent; suitable for trace water detection. |
| Melting Point | Melting Point Determination (Capillary Method or Automated Melting Point Apparatus) | Determine the temperature range at which the compound transitions from solid to liquid, used to evaluate purity and consistency. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After digesting the sample, measure residual levels of heavy metals such as lead, arsenic, mercury, and cadmium to ensure compliance with pharmacopeial or industrial standards. |
| Sulfate Residue | Ion Chromatography (IC) or Turbidimetric Method | Detect sulfate ions that may remain from the synthesis process, evaluating the effectiveness of washing and purification steps. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Analyze potential impurities such as synthetic intermediates, by-products, or degradation products (e.g., unreacted starting materials, oxidized compounds). |
| pH Value (aqueous solution) | pH Meter Method | Prepare an aqueous solution of defined concentration (e.g., 1% w/v) and measure acidity or alkalinity using a calibrated pH meter. |
| Residue on Ignition | Sulfated Ash Method | Weigh the residue remaining after high-temperature ignition of the sample to estimate total inorganic impurities. |
