| Agrochemicals | Intermediate for fungicidal agents; applied in developing novel pyrazole-based agricultural fungicides | Applied in cyclization, halogenation, and coupling reactions to build active molecules containing the pyrazole–acetophenone scaffold |
| Materials Science | Precursor for dopants in OLED emissive or electron-transport layers | Brominated and subjected to Suzuki coupling to introduce conjugated groups, thereby tuning HOMO/LUMO energy levels and thermal stability |
Manufacturing Quality Control of 1-[4-(1H-PYRAZOL-1-YL)PHENYL]ETHANONE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at 254 nm, comparing peak area to a certified reference standard. |
| Related Substances | HPLC-UV | Separation and quantification of impurities using gradient HPLC-UV; identification based on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Headspace GC with flame ionization detection to quantify common organic solvents (e.g., acetone, methanol, ethyl acetate) per ICH Q3C guidelines. |
| Water Content | Karl Fischer Titration | Electrochemical titration using iodine generated in situ to react stoichiometrically with water in the sample. |
| Heavy Metals | ICP-MS | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, with detection at sub-ppt levels. |
| Chloride Impurity | Ion Chromatography | Separation and conductivity detection of chloride ions following aqueous extraction and filtration. |
| Sulfated Ash | Gravimetric Analysis | Ignition at 700-800 C followed by weighing of residual inorganic ash after sulfuric acid treatment. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using calibrated capillary method per USP <741>. |
| Appearance | Visual Inspection | Assessment of physical state, color, and clarity against established reference standards under controlled lighting. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation of plane-polarized light induced by chiral centers; reported as [alpha]D value at specified concentration and temperature. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to determine volume-based particle size distribution in dispersed dry or wet samples. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Determination of hydrogen ion activity in a defined saturated aqueous suspension using a calibrated glass electrode. |
