Manufacturing Quality Control of N-Hydroxy-5-norbornene-2,3-dicarboximide
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, condition, and presence of visible impurities in the sample. Usually appears as a white to off-white crystalline powder. |
| Purity (Main Component Content) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 chromatography column with a UV detector (e.g., 220 nm or 254 nm), quantitatively analyze the purity of the target compound based on retention time and peak area. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Use ¹H NMR and ¹³C NMR to confirm the compound structure, identify characteristic peaks, and verify molecular structure accuracy. |
| Structural Confirmation | Fourier Transform Infrared Spectroscopy (FTIR) | Analyze characteristic absorption peaks of functional groups such as N–OH, C=O (amide), C=C, etc., used for auxiliary structural identification. |
| Molecular Weight Confirmation | Mass Spectrometry (MS) | Use ESI-MS or EI-MS to determine the molecular ion peak, confirm molecular weight and major fragment ions, and verify the presence of the target compound. |
| Moisture Content | Karl Fischer Titration | Accurately determine the moisture content in the sample, suitable for moisture-sensitive active compounds to ensure storage stability. |
| Residual Solvents | Gas Chromatography (GC) | Detect residual organic solvents (such as ethanol, acetone, dichloromethane, etc.) from the synthesis process, ensuring compliance with pharmacopoeia limits. |
| Melting Point | Melting Point Apparatus Method | Determine the melting temperature range of the compound, used for preliminary judgment of purity and consistency. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | Detect heavy metal residues such as lead, mercury, cadmium, and arsenic, ensuring compliance with safety standards (especially for pharmaceutical intermediates). |
| Microbial Limit | Microbial Limit Test | If used in pharmaceutical or bioconjugation fields, detect microbial contamination such as bacteria and mold (applicable for non-sterile products). |
