Industrial Applications of 4-PHENYL-1H-PYRAZOL-5-AMINE
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Chemicals | Synthetic intermediate for pharmaceuticals | Serves as a key building block in coupling or cyclization reactions to synthesize pyrazole-containing drug molecules. |
| Pharmaceutical Chemicals | Kinase inhibitor development | Used in constructing small-molecule inhibitors targeting specific kinases (e.g., CDK, JAK), leveraging its amino group and pyrazole core structure. |
| Chemical Reagents | Bio-probe synthesis | Acts as an active reaction site in the synthesis of functional dyes or biomarker molecules. |
| Organic Synthesis | Heterocyclic compound construction | Undergoes acylation or alkylation via nucleophilic amino group, or serves as a pyrazole scaffold for constructing more complex fused-ring systems. |
Manufacturing Quality Control of 4-PHENYL-1H-PYRAZOL-5-AMINE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separates and quantifies impurities by HPLC-UV using gradient elution and relative response factors or external standards. |
| Residual Solvents | GC-FID | Detects and quantifies volatile organic solvents (e.g., ethanol, acetone) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generation in pyridine/methanol-based reagent. |
| Heavy Metals | ICP-OES | Measures total elemental metal content (e.g., Pb, Cd, Ni, Fe) after acid digestion using inductively coupled plasma optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Quantifies chloride ions using suppressed conductivity detection after separation on an anion-exchange column. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion of sample with sulfuric acid followed by high-temperature ashing and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against defined reference standards. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a saturated aqueous suspension (1% w/v) using calibrated pH electrode per EP 2.2.3. |
| Loss on Drying | Thermogravimetric Analysis | Determines volatile matter loss by measuring mass change upon heating at 105 C for 2 hours under controlled airflow. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of dry powder using Mie scattering theory applied to laser light diffraction patterns. |
