Industrial Applications of 4-bromo-1-methylpyrazole-3-carboxy acid
| Industry | Application | Process |
|---|---|---|
| Pesticides | Key intermediate for novel insecticides and acaricides | Used in the synthesis of pyrazole-containing agrochemical active ingredients, such as fluopyram derivatives, via coupling or cyclization reactions with amine compounds |
| Pharmaceuticals | Synthetic intermediate for anti-inflammatory and anticancer drug candidates | Employed to construct pyrazole-ring-containing drug scaffolds; commonly applied in Suzuki coupling, ester hydrolysis, and amidation reactions to introduce pharmacophores |
| Materials Science | Building block for organic light-emitting diode (OLED) functional materials | Serves as a precursor for electron-transport/hole-blocking layer materials; bromine functional groups are converted (e.g., to boronic esters) for cross-coupling polymerization or small-molecule modification |
Manufacturing Quality Control of 4-bromo-1-methylpyrazole-3-carboxy acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to certified reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient HPLC-UV; identification based on retention time relative to reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, ethyl acetate) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine-based reagent reacting stoichiometrically with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pb, Cd, Ni) after acid digestion by inductively coupled plasma mass spectrometry with isotopic detection. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after high-temperature combustion (700-800 C) followed by weighing of residual ash. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry powder particle size distribution by measuring angular scattering pattern of laser beam passing through dispersed sample. |
| Bulk Density | USP <1174> Tap Density Test | Measures mass per unit volume of powder before and after standardized mechanical tapping to assess flow and packing behavior. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determines pH of saturated aqueous suspension using calibrated pH electrode per USP <791>. |
| Organic Volatile Impurities (OVI) | GC-MS | Identifies and quantifies unspecified volatile organic impurities using gas chromatography coupled with mass spectrometric detection. |
