| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with standard spectra to confirm the presence of characteristic functional groups in methylenedioxymethane (e.g., hydroxyl, methylene groups). |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyze the chemical shifts and coupling constants of hydrogen atoms using nuclear magnetic resonance to verify the structural characteristics of methylenedioxymethane. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 chromatographic column with an appropriate mobile phase (such as methanol-water or acetonitrile-water) for separation, and quantitatively determine the content of methylenedioxymethane using a UV detector (typically 210–220 nm). |
| Gas Chromatography (GC) | For derivatives with good volatility (such as silylated samples), GC-FID can be used for quantitative analysis. | |
| Related Substances/Impurities | High-Performance Liquid Chromatography (HPLC) | Use a gradient elution program to separate and detect possible process impurities or degradation products. Calculate the impurity content using area normalization or correction factor methods. |
| Moisture | Karl Fischer Method | Determine the moisture content of the sample using potentiometric or coulometric titration, suitable for organic compounds with low water content. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection with a capillary column and FID detector to detect residual organic solvents from the production process (e.g., methanol, acetone, etc.). |
| Melting Point | Melting Point Determination | Determine the melting range of the sample using a melting point apparatus to assess purity and crystalline consistency. |
| Specific Rotation (if applicable) | Polarimetry | If methylenedioxymethane is a chiral compound or its specific isomer, measure its specific rotation using a polarimeter for identification and purity evaluation. |
