Manufacturing Quality Control of 4,6-DICHLORO-5-NITRO-2-PROPYLTHIOPYRIMIDINE
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Identification (Identity) | Infrared Spectroscopy (IR) | Compare the infrared absorption spectrum of the sample with a reference spectrum to confirm the presence of characteristic functional groups (e.g., C–Cl, NO₂, C–S). |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyze chemical shifts, integration areas, and coupling constants of hydrogen atoms to verify molecular structure. | |
| Assay (Content Determination) | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with UV detection (typically at 254 nm or based on maximum absorption wavelength), quantifying the main component using external standard method. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Same conditions as assay or optimized gradient elution program to separate and quantify potential process impurities, degradation products, etc.; typically calculated by area normalization or with correction factors. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Constant Temperature Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight, measuring the percentage loss due to volatile substances (including moisture). |
| Residual Solvents | Gas Chromatography (GC) | Use headspace or direct injection with FID detection; detect organic solvents (e.g., dichloromethane, toluene) remaining from synthesis according to ICH Q3C guidelines. |
| Melting Point | Capillary Melting Point Method | Determine the temperature range from initial melting to complete melting as an auxiliary indicator for purity and identity. |
| Appearance and Color | Visual Color Comparison Method | Observe the sample under specified lighting conditions to ensure it appears as a white to off-white crystalline powder without abnormal coloration. |
| pH (if applicable) | pH Meter Measurement | If the sample is soluble in water or a specific solvent, prepare a solution at a defined concentration and measure pH to assess the impact of acidic or basic impurities. |
| Heavy Metals | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, detect elemental impurities such as lead, cadmium, mercury, and arsenic, ensuring compliance with pharmacopoeial or ICH Q3D limits. |
