Manufacturing Quality Control of Bis-(sodium sulfopropyl)-disulfide
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Place an appropriate amount of sample into a colorimetric tube or petri dish against a white background, and observe its color, physical state, and presence of impurities under natural light or a standard light source. The sample should appear as white to off-white powder or crystalline powder. |
| Identification | Infrared Spectroscopy (IR) Ion Chromatography (IC) |
1. Infrared Spectroscopy (IR): Prepare a KBr pellet of the sample, record its infrared absorption spectrum, and compare it with the reference spectrum to confirm the presence of characteristic functional groups (e.g., sulfonic acid group, C–S bond). 2. Ion Chromatography (IC): Separate using anion-exchange chromatography to detect the presence of propane sulfonate ions in the sample; identification is based on retention time comparison. |
| Assay | High-Performance Liquid Chromatography (HPLC) Potentiometric Titration |
1. HPLC Method: Use a reversed-phase C18 column with a mobile phase such as phosphate buffer-acetonitrile mixture. Detection is performed using a UV detector (typically at 200–220 nm), and quantification is achieved by external standard method. 2. Potentiometric Titration: Utilize the acidic nature of the sulfonic acid group in sodium polythiodipropyl sulfonate, titrate with standardized sodium hydroxide solution, and calculate the content based on the titration endpoint. |
| pH Value | pH Meter Method | Prepare an aqueous solution of defined concentration (e.g., 1% w/v), and measure the pH at 25°C using a calibrated pH meter. The result should fall within the specified range (typically 4.0–7.0). |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Atmospheric Drying Method | Dry the sample at 105°C until constant weight is achieved, then calculate the percentage weight loss to assess moisture and volatile content. Typically, the limit is ≤1.0%. |
| Sulfated Ash / Residue on Ignition | Gravimetric Method | The sample is ignited at high temperature (approximately 700–800°C), and the remaining inorganic residue is weighed to determine total inorganic impurities. The limit is typically ≤0.1%. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) |
After acid digestion of the sample, heavy metal elements such as lead, arsenic, cadmium, and mercury are determined by AAS or ICP-MS. The total heavy metal content is generally limited to no more than 10 ppm (parts per million). |
| Chlorides | Silver Nitrate Turbidimetric Method | The sample solution is acidified with nitric acid, then treated with silver nitrate reagent. The resulting turbidity is compared with that from a standard sodium chloride solution to control chloride ion impurity levels. |
| Sulfates | Turbidimetric Method (Barium Sulfate Method) | In a hydrochloric acid medium, barium chloride is added to form barium sulfate precipitate. The turbidity is compared with that from a standard potassium sulfate solution to control sulfate ion impurities. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use gradient elution HPLC conditions to separate the main component from potential degradation products or synthesis by-products (e.g., monomers, oxidation products). Individual impurity levels are calculated using area normalization or a main component self-reference method with correction factors. |
