Manufacturing Quality Control of Methyl 2,2-difluoro-2-(fluorosulfonyl)acetate
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color and state of the sample under natural light or standard light sources to determine whether it is a clear, transparent liquid and whether there are any suspended particles or precipitates. |
| Content (Purity) | Gas Chromatography (GC) | Capillary column gas chromatography with a hydrogen flame ionization detector (FID) is used. Qualitative analysis is based on retention time, while quantitative analysis is performed using peak area normalization or external standard method to determine the main component content. |
| Moisture | Karl Fischer Titration | Iodine reacts quantitatively with water in the presence of sulfur dioxide, pyridine, and methanol. The moisture content in the sample is determined by coulometric titration, suitable for trace moisture detection. |
| Acid Value (or Free Acid) | Acid-Base Titration | A standard sodium hydroxide ethanol solution is used for titration, with phenolphthalein as an indicator, to calculate the content of free acid (e.g., fluorsulfonyl difluoroacetic acid produced during hydrolysis). |
| Residual Solvents | Gas Chromatography (GC) | Headspace gas chromatography (HS-GC) is employed to detect organic solvents (such as methanol, dichloromethane, etc.) that may remain from the production process. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | 19F NMR and 1H NMR are used to confirm molecular structure, particularly the positions and quantities of fluorine atoms and methyl groups, to verify the target compound's structure. |
| Infrared Spectrum (IR) | Fourier Transform Infrared Spectroscopy (FT-IR) | Characteristic absorption peaks (such as S=O, C=O, C-F, etc.) are used to verify the presence of functional groups, assisting in structural identification and impurity screening. |
| Impurity Analysis | High-Performance Liquid Chromatography-Mass Spectrometry (HPLC-MS) or GC-MS | Separte and identify possible byproducts or degradation products (such as hydrolysis products, ester exchange products, etc.), enabling qualitative and quantitative analysis of trace impurities. |
| Density | Densitometer Method or Pycnometer Method | Measure the mass per unit volume at a specified temperature (e.g., 20°C) for physical property monitoring. |
| Refractive Index | Refractometer Method | Use an Abbe refractometer to measure the refractive index of the sample at a specific temperature, serving as an auxiliary identification parameter. |
