| Dyes | Intermediate for azo dyes and functional dyes | Diazotized, then coupled with phenols or aromatic amines to yield colored compounds |
| Materials Science | Building block for electron-transport materials in organic light-emitting diodes (OLEDs) | Integrated into conjugated backbones via Suzuki coupling or Ullmann reaction to tune energy-level alignment |
Manufacturing Quality Control of 2-Amino-3-nitropyridine
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state (e.g., white or off-white crystalline powder) and presence of foreign matter with the naked eye to determine whether it meets specified requirements. |
| Identification | Infrared Spectroscopy (IR) High-Performance Liquid Chromatography (HPLC) Proton Nuclear Magnetic Resonance (¹H NMR) |
- IR: Measure the infrared absorption spectrum of the sample and compare characteristic absorption peaks (e.g., nitro group, amino group, pyridine ring functional groups) with reference spectra. - HPLC: Compare retention times of test sample and reference standard under specific chromatographic conditions. - ¹H NMR: Confirm molecular structure by analyzing chemical shifts and coupling constants of hydrogen atoms in the nuclear magnetic resonance spectrum. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with mobile phases such as methanol-water or acetonitrile-buffer salt systems. Detect using UV detector (typically at 254 nm or based on maximum absorption wavelength). Calculate main component content using external standard method or area normalization method. Typically requires ≥98.0%, or according to pharmacopoeia or enterprise standards. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Employ gradient or isocratic elution programs to separate and detect potential process impurities and degradation products (e.g., unreacted raw materials, by-products). Quantify using self-control method or main component self-control method with correction factors. Control limits for individual and total impurities. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Constant Temperature Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight, then calculate the percentage of mass loss to assess moisture and volatile substance content. Typically requires ≤0.5%. |
| Residue on Ignition | Gravimetric Method | Ignite the sample at high temperature (approximately 700–800°C), then weigh the residual ash to control inorganic impurities (e.g., metal salts). Generally requires ≤0.1%. |
| Water Content | Karl Fischer Titration | Use either volumetric or coulometric Karl Fischer titration to specifically determine water content. Suitable for thermally unstable compounds or those containing hydrated water. Typically requires ≤0.5%. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace injection or direct injection with polar or non-polar capillary columns and FID detection to measure organic solvents potentially remaining from synthesis (e.g., methanol, ethanol, dichloromethane, DMF). Control levels according to ICH Q3C guidelines. |
