Industrial Applications of 941685-27-4
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthetic intermediate for drug manufacturing | Used in the synthesis of kinase inhibitor-based anticancer drugs |
| Biochemical Research | Synthesis of biomarkers and probes | Functionalization reactions to conjugate fluorescent or other functional groups |
| Agrochemicals | Precursor compound for active pharmaceutical ingredients (APIs) | Involved in constructing heterocyclic agrochemical molecular frameworks |
Manufacturing Quality Control of 941685-27-4
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, presence of caking, or visible foreign matter under natural or standard lighting conditions. |
| Identification | HPLC / FT-IR / NMR | HPLC: Compare retention time with reference standard; FT-IR: Match characteristic functional group absorption peaks; NMR: Confirm structural consistency using nuclear magnetic resonance spectroscopy. |
| Assay (Content Determination) | HPLC (External or Internal Standard Method) | Use reversed-phase high-performance liquid chromatography (e.g., C18 column) with a UV detector (typically at 254 nm or at the wavelength of maximum absorption) to quantify the main component. |
| Related Substances (Impurity Analysis) | HPLC (Gradient Elution) | Detect organic impurities in the active pharmaceutical ingredient (e.g., degradation products, by-products, residual starting materials); impurities ≥0.1% are typically required to be reported. |
| Residual Solvents | GC (Headspace Injection) | Detect volatile organic solvents used in manufacturing (e.g., methanol, ethanol, dichloromethane, DMF, tetrahydrofuran), in accordance with ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Precisely measure water content in the sample; suitable for moisture-sensitive compounds to ensure stability. |
| Sulfated Ash (Residue on Ignition) | Gravimetric Method | Weigh the residue after high-temperature ignition of the sample to evaluate inorganic impurity levels; typically limited to ≤0.1%. |
| Heavy Metals | ICP-MS or Thioglycolate Method (Chinese Pharmacopoeia) | ICP-MS offers high sensitivity and simultaneous multi-element detection; the thioglycolate method is a traditional colorimetric test for heavy metals such as lead. |
| Melting Point | Capillary Method / DSC | The capillary method is simple and fast; DSC (Differential Scanning Calorimetry) provides more accurate melting behavior and purity information. |
| Polymorph Analysis | XRD / DSC / TGA | XRD is used to identify different crystalline forms; DSC and TGA assist in determining hydration/solvation and thermal stability. |
| Particle Size Distribution | Laser Diffraction (LDI) | Evaluate the particle size distribution of solid powders, which affects solubility and formulation performance, especially important in solid dosage form development. |
