Industrial Applications of 1H-Pyrazole,5-bromo-1-methyl-(9CI)
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Used as a pharmaceutical intermediate in the synthesis of antiviral, antitumor, or anti-inflammatory compounds | Applied to construct pyrazole-containing active molecules via nucleophilic substitution and coupling reactions (e.g., Suzuki, Buchwald–Hartwig) |
| Agrochemicals | Used as an agrochemical intermediate in the synthesis of pyrazole derivatives with insecticidal or fungicidal activity | Applied to introduce functional groups into the target agrochemical scaffold via halogen–metal exchange or transition metal-catalyzed coupling |
| Organic Synthesis | Used as a versatile synthon for constructing complex heterocyclic systems | Applied to form C–C or C–N bonds leveraging the reactivity of the bromine atom, such as palladium-catalyzed cross-coupling or electrophilic trapping after lithiation |
Manufacturing Quality Control of 1H-Pyrazole,5-bromo-1-methyl-(9CI)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 220-254 nm based on peak area comparison to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., starting materials, isomers, dehalogenated by-products) using gradient HPLC-UV against qualified impurity standards. |
| Residual Solvents | GC-FID | Measures trace organic solvents (e.g., methanol, ethyl acetate, toluene) by headspace GC with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine generated electrochemically or added reagent, based on stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Hg, As) after acid digestion using inductively coupled plasma mass spectrometry with isotopic detection. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after charring at 600-700 C and weighing the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary apparatus per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against standard reference. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume after standardized tapping per USP <616> to assess flow and handling characteristics. |
| Particle Size Distribution | Laser Diffraction | Analyzes particle size distribution in dry dispersion mode using Mie scattering theory and validated optical model. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a defined suspension (e.g., 1% w/v in water) using calibrated pH electrode with temperature compensation. |
