Manufacturing Quality Control of 2-Amino-3,6,8-naphthalenetrisulfonic acid
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, physical state, and presence of visible impurities. Typically appears as white to light yellow powder or crystals. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Uses a reverse-phase C18 column and a UV detector (e.g., 254 nm), with water-methanol or buffer solution as the mobile phase for quantitative analysis of the main component. |
| Purity (Related Substances) | High-Performance Liquid Chromatography (HPLC) | Uses HPLC to detect and separate potential organic impurities (e.g., unreacted starting materials, intermediates, or degradation products), and calculates the total impurity level. |
| Moisture Content | Karl Fischer Titration | Quantitatively determines water content using Karl Fischer reagent; suitable for moisture analysis of compounds containing sulfonic acid groups. |
| Sulfonic Acid Group Content | Ion Chromatography or Titration | Determines free sulfonate ion content via ion chromatography; or indirectly calculates total acidic group content by alkaline titration. |
| pH Value | pH Meter Measurement | Dissolve the sample in water and measure the solution's acidity or alkalinity using a calibrated pH meter to evaluate its aqueous solution properties. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determines residual levels of heavy metals such as lead, arsenic, cadmium, and mercury to ensure compliance with safety limits. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Method | Weighs the residue remaining after high-temperature ignition of the sample to assess inorganic impurity content, particularly suitable for sulfonic acid compounds. |
| Solubility | Solubility Test | Add the sample to solvents such as water or ethanol and observe dissolution behavior to determine whether it meets specified solubility requirements. |
| Melting Point | Melting Point Apparatus | Determine the melting temperature range using an automatic melting point instrument or capillary method to assist in assessing substance purity and consistency. |
