| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of pharmaceutical intermediates | Used in organic synthesis reactions |
| Agrochemicals | Preparation of active pharmaceutical ingredients (APIs) | Applied in catalytic coupling reactions |
| Materials Science | Development of functional polymers | Applied in polymerization reactions |
| Organic Synthesis Research | Laboratory reagent | Used in multi-step organic transformations |
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color and physical state (e.g., white to off-white crystalline powder) to determine if it matches the standard description. |
| Purity | High-Performance Liquid Chromatography (HPLC) | Use a C18 column with UV detection (e.g., 254 nm), calculate main peak purity using area normalization or external standard method. |
| Impurities | HPLC (Gradient Elution) | Separate and quantify potential process impurities or degradation products; set limits (e.g., individual impurity ≤0.1%, total impurities ≤0.5%). |
| Water Content | Karl Fischer Titration | Determine moisture content using coulometric or volumetric methods, ensuring compliance with loss on drying or water content specifications (e.g., ≤0.5%). |
| Residual Solvents | Gas Chromatography (GC, Headspace Injection) | Test for residual organic solvents (e.g., toluene, ethanol, DMF) from synthesis according to ICH Q3C guidelines; ensure quantitation limits meet requirements. |
| Melting Point | Capillary Melting Point Apparatus | Determine the melting temperature range (e.g., literature value ~85–88°C) to preliminarily assess purity and structural consistency. |
| Structural Confirmation | Nuclear Magnetic Resonance (NMR), Infrared Spectroscopy (IR), Mass Spectrometry (MS) | NMR (¹H/¹³C) confirms hydrogen and carbon framework; IR verifies functional groups; MS determines molecular weight; combined use confirms chemical structure. |
| Heavy Metals | ICP-MS or Atomic Absorption Spectroscopy | Test for element impurities such as lead, cadmium, mercury, and arsenic per pharmacopoeial methods; total content should not exceed 20 ppm. |
| Loss on Drying | Oven Drying Method | Dry sample at specified temperature (e.g., 105°C) until constant weight, measure percentage mass loss to assess volatile components. |
| Residue on Ignition | Furnace Ashing Method | Ignite sample at high temperature (600–800°C), weigh the residue to assess inorganic impurities (typically required ≤0.1%). |
| Test Item | Specification |
