Manufacturing Quality Control of 1,6-Naphthalenedisulfonic acid disodium salt
| Detection Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and visible impurities under natural light or standard illumination. Typically appears as a white to pale yellow powder or crystalline substance. |
| Content (Purity) | High-Performance Liquid Chromatography (HPLC) | Utilize a reversed-phase column (e.g., C18) with UV detection (~254 nm). Qualify the main component by retention time and quantify using external standard method based on peak area. |
| Moisture Content | Karl Fischer Titration | Based on the quantitative reaction between iodine and sulfur dioxide in the presence of pyridine and methanol with water, this method is used to determine moisture content in samples, particularly suitable for compounds containing sulfonic acid groups. |
| Residue on Ignition | Gravimetric Method (Sulfated Ash) | After treatment with sulfuric acid, the sample is subjected to high-temperature incineration. The mass of residual inorganic matter is weighed to calculate the percentage of residue, assessing the level of inorganic impurities. |
| pH Value | pH Meter Measurement | Dissolve 1,6-naphthalenedisulfonic acid sodium salt in water at a specified concentration (e.g., 1% w/v), then directly measure the acidity or alkalinity using a calibrated pH meter. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After digestion with nitric acid-peroxide hydrogen mixture, detect levels of heavy metals such as lead, arsenic, mercury, and cadmium; results must comply with pharmacopoeial or industrial standards. |
| Sulfonic Acid Group Content | Acid-Base Titration | Convert sulfonic acid groups into H⁺ form under appropriate conditions, then titrate with standardized NaOH solution. Calculate the equivalent number of sulfonic acid groups to verify structural consistency. |
| Organic Impurities / Related Substances | High-Performance Liquid Chromatography (HPLC) | Similar to content determination, use HPLC to detect impurity peaks other than the main peak. Evaluate total impurities using either the area normalization method or reference standard method. |
| Particle Size Distribution | Laser Particle Size Analysis | Disperse the sample in a liquid medium and apply laser scattering principles to measure particle size distribution, used to assess solubility and process performance. |
| Solubility | Solubility Test | Take a small amount of sample and add it to water, ethanol, or other solvents, shake vigorously, and observe dissolution behavior to evaluate solubility in different solvents. |
