Manufacturing Quality Control of 3,5-Difluoropyridine-2,6-diamine
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state (e.g., white to off-white powder), and check for caking or visible impurities. |
| Purity and Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a UV detector (typically around 254 nm) to determine purity and content of the main component via external standard method or area normalization method. |
| Structural Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | Use ¹H NMR and ¹⁹F NMR to confirm the compound’s structure by verifying the chemical environments of hydrogen and fluorine atoms are consistent with the target structure. |
| Structural Confirmation | Mass Spectrometry (MS) | Employ electrospray ionization (ESI) or electron ionization (EI) mass spectrometry to detect the molecular ion peak and verify that the molecular weight matches the target compound (C₅H₅F₂N₄). |
| Moisture Content | Karl Fischer Titration | Quantitatively determine water content in the sample using Karl Fischer reagent; suitable for organic intermediates sensitive to moisture. |
| Residual Solvents | Gas Chromatography (GC) | Detect organic solvents possibly remaining from manufacturing (e.g., methanol, ethanol, acetone, dichloromethane), with limits based on ICH guidelines. |
| Melting Point | Melting Point Determination (Capillary Method or DSC) | Determine the melting temperature range using a melting point apparatus, useful for preliminary assessment of purity and consistency; differential scanning calorimetry (DSC) can provide more precise measurement. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | Determine residual levels of heavy metals such as lead, arsenic, mercury, and cadmium to ensure compliance with pharmaceutical or high-purity chemical standards. |
| Residue on Ignition (Sulfated Ash) | Gravimetric Method | Ignite the sample at high temperature with sulfuric acid treatment and measure the weight of non-volatile inorganic residue. |
| pH Value (in Solution) | pH Meter Method | Dissolve the sample in a suitable solvent (e.g., water or dilute ethanol) and measure the acidity or alkalinity using a calibrated pH meter. |
