Manufacturing Quality Control of 4,4'-Diaminobenzenesulphanilide
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state under natural light or standard illumination to determine if it is a white to pale yellow crystalline powder, and check for impurities, agglomeration, etc. |
| Melting Point | Capillary Melting Point Determination | Determine the melting temperature range using a melting point apparatus, and compare with the standard value (approximately 178–182 °C) to assess purity. |
| Content (Main Component) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with UV detection (e.g., 254 nm), quantifying the main component content via external standard or internal standard method to evaluate purity. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Utilize gradient elution to separate potential synthetic intermediates, oxidation products, or by-products; calculate peak areas of each impurity and control within specified limits. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Oven Method | Dry the sample at 105 °C until constant weight, then measure the percentage of weight loss to reflect moisture and volatile impurity content. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Analysis | After high-temperature incineration, weigh the inorganic residue and calculate its percentage relative to the original sample weight, used to control inorganic impurities. |
| Water Content | Karl Fischer Titration | Use a KF titrator to precisely determine the water content in the sample, suitable for trace moisture analysis. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Digest the sample and measure levels of lead, arsenic, cadmium, mercury, and other heavy metals to ensure compliance with pharmaceutical or industrial standards. |
| Solubility | Solubility Test | Observe the sample’s solubility in solvents such as water, ethanol, acetone, dilute acids, etc., serving as auxiliary identification and quality reference. |
| Structural Confirmation | Fourier Transform Infrared Spectroscopy (FT-IR) or Nuclear Magnetic Resonance (NMR) | Perform FT-IR or ¹H/¹³C NMR analysis on the raw material to confirm whether characteristic peaks match those in the reference spectrum. |
