| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Key intermediate for JAK2 kinase inhibitors, used in the treatment of hematologic disorders such as myeloproliferative neoplasms | Acts as the core aromatic amine structural unit in pyrimidoimidazole-based JAK2 inhibitors; couples with halogenated heterocyclic fragments via cross-coupling reactions (e.g., Buchwald–Hartwig amination) |
| Agrochemicals | Structural building block for novel insecticidal and fungicidal candidate compounds | Introduces a hydrophobic–hydrogen-bonding pharmacophore containing both trifluoromethyl and imidazolyl groups; employed in structural optimization and structure–activity relationship (SAR) studies of bioactive molecules |
| Materials Science | Building block for organic optoelectronic functional materials | Serves as an amine-terminated modification component in donor–acceptor (D–A) type conjugated polymers or small molecules, used to tune HOMO energy levels and thin-film morphology |
| 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) under natural light or standard illumination to determine compliance with specifications. |
| Identification | Infrared Spectroscopy (IR) High-Performance Liquid Chromatography (HPLC) Proton Nuclear Magnetic Resonance (¹H NMR) |
IR: Compare the infrared absorption spectrum of the sample with that of the reference standard; HPLC: Under specific chromatographic conditions, compare the retention time of the main peak with that of the reference substance; ¹H NMR: Confirm molecular structure based on characteristic chemical shifts and coupling constants. |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with mobile phase consisting of methanol-water or acetonitrile-buffer salt system, detected by UV detector (e.g., 254 nm). Quantify the main component using external standard method; typically requires ≥98.0%. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Employ gradient elution to separate the main component from potential impurities (e.g., starting materials, intermediates, degradation products). Control individual and total impurity levels using area normalization or the main component self-control method with correction factors (e.g., individual impurity ≤0.5%, total impurities ≤1.0%). |
| Residual Solvents | Gas Chromatography (GC) | Use headspace injection or direct injection with a polar capillary column (e.g., DB-624), detected by FID. Detect residual organic solvents (e.g., methanol, dichloromethane, toluene) from synthesis or purification processes, following ICH Q3C guidelines for specified limits. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Constant Weight Method | Dry the sample at 105°C until constant weight, then calculate the percentage of mass loss to assess moisture and volatile content (typically ≤0.5%). |
| Residue on Ignition | Gravimetric Method | Ignite the sample at high temperature (700–800°C), then weigh the residual inorganic matter. Used to control inorganic impurities (typically ≤0.1%). |
| Water Content | Karl Fischer Titration | Determine water content using either volumetric or coulometric Karl Fischer titration, suitable for moisture-sensitive compounds. Typically requires ≤0.5%. |
