Manufacturing Quality Control of 4-Bromo-1-isopropyl-1H-pyrazole
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specified wavelength using reverse-phase C18 column and calibrated standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., starting materials, isomers, dehalogenated products) via gradient elution and peak area comparison. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., acetone, toluene, DMF) using capillary column separation and flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine generated electrochemically or added stoichiometrically. |
| Heavy Metals | ICP-MS | Quantifies trace metals (e.g., Pd, Ni, Fe) after acid digestion using inductively coupled plasma mass spectrometry for high sensitivity. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing at 700-800 C and weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube and controlled heating rate. |
| Optical Rotation | Polarimetry | Measures specific rotation of chiral impurities or enantiomeric excess using sodium D-line light through a solution cell. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample by measuring angular intensity of scattered laser light to calculate size distribution. |
| Bulk Density | USP <616> Tap Density Test | Determines mass per unit volume after mechanical tapping of powder in a graduated cylinder to simulate handling behavior. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Measures hydrogen ion activity in saturated aqueous suspension using calibrated glass electrode and reference electrode. |
