Manufacturing Quality Control of 5-Amino-1-naphthalenesulfonic acid
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, condition (e.g., whether it is a white to light gray crystalline powder) and presence of visible impurities using the naked eye to determine if the appearance meets quality standards. |
| Purity/Content | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 chromatographic column with an appropriate proportion of methanol-water or acetonitrile-water as the mobile phase. Detect using a UV detector (typically at 254 nm or 280 nm wavelength). Calculate the content of 5-aminonaphthalene-1-sulfonic acid using external or internal standard methods based on peak area to evaluate its purity. |
| Dry Loss | Thermogravimetric Analysis (TGA) or Constant Pressure Constant Temperature Drying Method | Dry the sample at a specified temperature (e.g., 105 °C) until constant weight is achieved, measure the percentage of mass loss to control the moisture and volatile substance content. |
| Residue on Ignition (Ash Content) | High-Temperature Incineration Method | Incinerate the sample in a high-temperature muffle furnace (usually 700–800 °C) until constant weight is achieved, weigh the residual inorganic matter to assess the content of inorganic impurities. |
| pH Value | pH Meter Measurement Method | Prepare a solution of 5-aminonaphthalene-1-sulfonic acid at a certain concentration (e.g., 1% w/v), then use a calibrated pH meter to measure the pH value, reflecting the acidity or alkalinity of the sample and possible acidic or basic impurities. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After digestion of the sample, use AAS or ICP-MS to determine the content of heavy metals such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmacopoeia or industry limit requirements. |
| UV-Visible Absorption Spectrum Characteristics | UV-Visible Spectrophotometry (UV-Vis) | Prepare a solution of the sample at a certain concentration and scan the absorption spectrum between 200–400 nm wavelengths to verify whether the maximum absorption wavelength (λmax) matches the standard, used for identification and preliminary purity assessment. |
| Melting Point | Capillary Melting Point Determination Method | Measure the melting point range of the sample using a melting point apparatus or Thiele tube method, compare it with the literature value (approximately 230–235 °C, decomposition), to assist in judging purity and structural consistency. |
