Industrial Applications of 4-FLUORO (1H)INDAZOLE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as a pharmaceutical intermediate in the synthesis of compounds exhibiting antitumor, anti-inflammatory, or central nervous system activity | Introduced as a 4-fluoro-1H-indazole structural motif into multistep organic syntheses via fluorination, cyclization, or coupling reactions |
| Agrochemicals | Employed as a lead compound for developing novel insecticides or fungicides | Applied as a heterocyclic scaffold to construct biologically active molecular structures through substitution or condensation reactions |
| Chemical Research | Utilized as a functionalized heterocyclic building block in organic synthesis for exploring new drug candidates or material properties | Modified structurally via metal-catalyzed coupling (e.g., Suzuki, Buchwald–Hartwig), nucleophilic substitution, or rearrangement reactions |
Manufacturing Quality Control of 4-FLUORO (1H)INDAZOLE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification via retention time matching and threshold-based reporting. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., acetone, methanol, toluene) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration with iodine-based reagent, based on stoichiometric electrochemical reaction. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni, As) after acid digestion using inductively coupled plasma mass spectrometry with isotope dilution. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion with sulfuric acid treatment and high-temperature incineration to constant weight. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid phase transition using calibrated capillary tube method per USP <741>. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light source to assess chiral purity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder size distribution by measuring angular scattering pattern of laser beam passing through dispersed sample. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated glass electrode pH meter. |
| Microbial Contamination | Membrane Filtration | Detects aerobic microorganisms by filtering sample solution, culturing on soybean-casein digest agar, and counting colony-forming units. |
