| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of pharmaceutical intermediates | Used in organic synthesis reactions |
| Pesticides | Preparation of pesticide active ingredients | Applied in coupling or substitution reactions |
| Materials Science | Development of functional material precursors | Employed in metal-catalyzed coupling or cyclization reactions |
| Chemical Research | Laboratory reagent | Utilized in multistep organic synthesis |
| Detection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Infrared Spectroscopy (IR) | Determine the infrared absorption spectrum of the sample and compare it with standard spectra to confirm characteristic functional groups and molecular structure of 5-bromo-1H-pyrazolo[3,4-c]pyridine. |
| Proton Nuclear Magnetic Resonance (¹H NMR) | Analyze chemical shifts, coupling constants, and other information of hydrogen atoms using nuclear magnetic resonance technology to verify the molecular structure. | |
| Content Determination | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with methanol-water or acetonitrile-water as the mobile phase, and UV detection (e.g., 254 nm). Quantify the main component using external standard or internal standard method. |
| Related Substances (Impurity) Testing | High-Performance Liquid Chromatography (HPLC) | Separate the main peak from potential impurities using gradient elution program. Control individual impurity limits by area normalization method or the main component self-control method with correction factors. |
| Residual Solvents | Gas Chromatography (GC) | Use headspace injection or direct injection with polar or nonpolar capillary columns and FID detector. Determine residual organic solvents (e.g., dichloromethane, methanol, DMF) from synthesis processes according to the Chinese Pharmacopoeia or ICH guidelines. |
| Drying Loss | Thermogravimetric Analysis (TGA) or Constant-Pressure Drying Method | Dry the sample at a specified temperature (e.g., 105°C) until constant weight, and measure the percentage of mass loss due to moisture or other volatile components. |
| Melting Point | Capillary Melting Point Determination | Determine the temperature range from initial melting to complete melting using a melting point apparatus as an auxiliary indicator for purity and identity. |
| Water Content | Karl Fischer Titration | Accurately determine trace water content in the sample using potentiometric or coulometric titration. Suitable for quality control of moisture-sensitive active pharmaceutical ingredients. |
