Manufacturing Quality Control of Diallyldisulfide
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Purity Assay | Gas Chromatography (GC) | Uses a capillary column for separation and FID detector for quantification. Purity is calculated by comparing peak areas with those of standard substances. This is the most commonly used method for purity analysis of DADS. |
| Content Determination | Gas Chromatography-Mass Spectrometry (GC-MS) | Combines the high separation capability of GC with the structural identification ability of MS, enabling accurate quantification and confirmation of the target compound. Suitable for content determination of DADS in complex matrices. |
| Impurity Analysis | GC-MS or HPLC-MS | Identifies structures of unknown impurities via mass spectra, and evaluates the presence and levels of by-products or degradation products by comparing retention times with reference standards. |
| Residual Volatile Organic Compounds | Headspace Gas Chromatography (HS-GC) | Detects residual solvents or low-boiling-point impurities. The sample is heated to equilibrium, and the headspace gas is injected for analysis, minimizing matrix interference. Ideal for analyzing volatile components. |
| Moisture Content | Karl Fischer Titration | Quantifies trace moisture in samples through titration reaction, ensuring storage stability of DADS and preventing hydrolysis or oxidative degradation. |
| Density | Densitometer or Pycnometer Method | Measures liquid density at a standard temperature (usually 20 °C) as a physical constant to assist in assessing product consistency. |
| Refractive Index | Abbe Refractometer | Determines refractive index at specific wavelength and temperature for rapid screening of batch-to-batch consistency and supporting purity assessment. |
| Appearance and Color | Visual Inspection or Colorimeter | Checks whether the sample is a clear, light yellow to amber liquid without suspended particles. A colorimeter can quantify Lab* values to ensure color meets specifications. |
| Acid Value/Acidity | Acid-Base Titration | Titrates free acids using phenolphthalein as indicator and standardized alkaline solution to control acidic impurity levels, preventing corrosion or instability. |
| Peroxide Value (Oxidation Level) | Iodometric Method or Potentiometric Titration | Evaluates whether oxidation has occurred during DADS storage. Elevated peroxide value indicates quality deterioration, necessitating control of packaging and storage conditions. |
