Industrial Applications of 4-CHLORO (1H)INDAZOLE
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate for antitumor agents and kinase inhibitors | Synthesized via nucleophilic substitution of 4-chloroindazole with amines, or via chlorination of the indazole ring |
| Agrochemicals | Active intermediate for synthesizing novel insecticides or fungicides | Bioactive molecules constructed from the 4-chloro-1H-indazole scaffold through acylation, sulfonylation, or coupling reactions |
| Chemical Research | Nitrogen-containing heterocyclic building block in organic synthesis | Used in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Buchwald–Hartwig) to prepare complex indazole derivatives |
Manufacturing Quality Control of 4-CHLORO (1H)INDAZOLE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reversed-phase HPLC with UV detection at 254 nm, comparing peak area against a certified reference standard. |
| Related Substances | HPLC-DAD | Separation and identification of impurities using HPLC coupled with diode array detection; relative retention times and UV spectra support structural assignment. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on calibrated response factors. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water; endpoint detected potentiometrically. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using mass spectrometry for high sensitivity and selectivity. |
| Chloride Ion Impurity | Ion Chromatography | Separation of anions on an ion-exchange column with suppressed conductivity detection; chloride quantified via calibration curve. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed visually or automatically as the solid-to-liquid phase change under controlled heating rate. |
| Loss on Drying | Gravimetric Analysis | Mass loss measured after drying under specified temperature and vacuum conditions; reflects volatile and moisture content. |
| Residue on Ignition | Sulfated Ash Test | Inorganic residue determined gravimetrically after high-temperature combustion of sample with sulfuric acid pretreatment. |
| Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light induced by chiral centers; confirms absence of racemization or chiral contamination. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity patterns to calculate volume-based particle size distribution in dispersed dry or wet samples. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | pH determined using a calibrated glass electrode in a saturated aqueous suspension, indicating acidic/basic impurity levels. |
