Manufacturing Quality Control of 5-amino-1,2-dihydropyrazol-3-one
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the color, state, and visible impurities of the sample under natural light or standard illumination. |
| Melting Point | Capillary Melting Point Method | Determine the initial and final melting points using a melting point apparatus to assess purity and characteristic properties. |
| Content (Main Component) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (e.g., 254 nm), identify compounds by retention time, and quantify using external standard method based on peak area. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Optimize mobile phase conditions to separate the main peak from impurity peaks. Calculate the area percentage of each impurity peak to evaluate purity and impurity limits. |
| Moisture | Karl Fischer Titration | Titrate the moisture in the sample using Karl Fischer reagent, suitable for the determination of trace moisture, providing accurate and reliable results. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Oven Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is achieved. Calculate the drying loss based on mass loss, reflecting the content of volatile components. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or solution injection, with capillary columns and FID detection, to detect residual organic solvents (such as methanol, ethanol) during production. |
| Ignited Residue | Ignited Residue Determination | Ignite the sample at high temperature (typically 700–800°C), and weigh the residue of inorganic matter to assess the content of inorganic impurities. |
| Heavy Metals | Atomic Absorption Spectrometry (AAS) or ICP-MS | After sample digestion, determine the levels of heavy metals such as lead, cadmium, mercury, and arsenic, ensuring compliance with pharmacopoeia or safety standards. |
| Structure Confirmation | Nuclear Magnetic Resonance (NMR), Infrared Spectroscopy (FT-IR), Mass Spectrometry (MS) | Use ¹H-NMR, ¹³C-NMR, FT-IR, and HRMS comprehensively to confirm the structure and functional groups of the compound. |
