| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Intermediates | Key building blocks in the synthesis of drug molecules | Synthesized via chemical reactions, typically including amination and nitration |
| Agrochemical Intermediates | Preparation of agrochemical compounds | Substitution or reduction reactions conducted under specific conditions |
| Organic Synthesis | Production of other organic compounds | Used as a feedstock in various organic synthesis reactions, such as coupling reactions |
| Test Item | Commonly Used Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection Method | Visually inspect the sample's color, physical state (e.g., white or off-white crystalline powder), and presence of foreign matter to determine if it meets standard specifications. |
| Identification | Infrared Spectroscopy (IR) High-Performance Liquid Chromatography (HPLC) |
IR: Measure the infrared absorption spectrum of the sample and compare it with the reference spectrum to confirm characteristic functional groups (e.g., amide, nitro, chlorobenzene, etc.); HPLC: Under specified chromatographic conditions, compare the retention time of the sample with that of the reference standard. |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with a mobile phase of methanol-water or acetonitrile-water. Detection is performed using a UV detector (typically at 254 nm or based on maximum absorption wavelength). The content of the main component is calculated using the external standard method to ensure the purity meets the requirement (e.g., ≥98.0%). |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Separate and detect possible process impurities and degradation products using gradient or isocratic elution. Quantification is performed using the area normalization method or the main component self-comparison method with correction factors, to control individual and total impurity limits. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Weight Drying Method under Normal Pressure | Dry the sample at a specified temperature (e.g., 105°C) until constant weight is reached. Measure the percentage mass loss to assess the content of moisture and volatile substances. |
| Residue on Ignition | High-Temperature Ignition Method | Ignite the sample at high temperature (usually 700–800°C) and weigh the residual inorganic material to control the total amount of inorganic impurities (e.g., metal salts, catalyst residues). |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection with an FID detector. Based on pharmacopoeia methods (e.g., ICH Q3C), detect residual organic solvents possibly present from the manufacturing process (e.g., toluene, dichloromethane, DMF, etc.), ensuring compliance with specified limits. |
| Melting Point | Capillary Melting Point Determination | Measure the temperature range from initial melting to complete melting using a melting point apparatus. Compare with the standard melting point (literature value approximately 160–164°C), serving as an auxiliary indicator for purity and identity. |
