Manufacturing Quality Control of 2-Naphthol-6-sulfonic acid potassium salt
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and physical state of the sample under natural or standard lighting to determine if it is a white to light yellow powder or crystalline substance, and check for visible impurities. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a mobile phase consisting of water and organic solvent (e.g., methanol or acetonitrile) in an appropriate ratio, containing ion-pair reagents or buffer salts. Detect using a UV detector (typically at 275–300 nm) and quantify the main component by external or internal standard method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Similar to assay determination, HPLC is used to separate and detect potential impurities such as synthesis intermediates, by-products, or degradation products. The percentage of each impurity peak area is calculated to assess purity. |
| Moisture Content | Karl Fischer Titration | Use coulometric or volumetric Karl Fischer titrator to accurately determine the water content in the sample. Suitable for moisture-sensitive compounds. |
| Sulfated Ash (Residue on Ignition) | Gravimetric Method | The sample is ignited at high temperature until constant weight. The residue consists mainly of inorganic salts (e.g., potassium sulfate). The weight of the residue is measured and expressed as a percentage to reflect inorganic impurity content. |
| pH Value | pH Meter Method | Dissolve the sample in water to a specified concentration (e.g., 1% w/v), then measure the pH using a calibrated pH meter to control the acidity or alkalinity of the solution. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After digestion with nitric acid and hydrogen peroxide, determine the levels of heavy metal elements such as lead, cadmium, mercury, and arsenic to ensure compliance with pharmaceutical or industrial safety standards. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Disperse the sample in liquid or gas and use laser scattering principles to measure particle size distribution. Applicable for powder formulations or control of reaction activity. |
| Infrared Identification | Fourier Transform Infrared Spectroscopy (FTIR) | Prepare the sample as a potassium bromide (KBr) pellet or use an ATR accessory to obtain the characteristic infrared absorption spectrum. Compare with reference spectrum to confirm chemical structure identity. |
