Manufacturing Quality Control of 4-BROMO-6-FLUORO (1H)INDAZOLE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities via gradient reverse-phase HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents using capillary GC with flame ionization detection and internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration based on iodine-sulfur dioxide redox reaction in pyridine-methanol medium. |
| Heavy Metals | ICP-MS | Measures trace metal contaminants (e.g., Pb, Cd, Ni) after acid digestion using inductively coupled plasma mass spectrometry. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion of sample with sulfuric acid followed by high-temperature incineration 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. |
| Appearance | Visual Inspection | Evaluates physical state, color, and presence of foreign particles under standardized white light against reference standards. |
| Particle Size Distribution | Laser Diffraction | Measures size distribution of solid particles in suspension by analyzing angular variation of scattered laser light intensity. |
| Optical Rotation | Polarimetry | Quantifies specific rotation using sodium D-line light passing through a solution in a temperature-controlled cell. |
| Residual Palladium | ICP-OES | Determines palladium content after microwave-assisted acid digestion using inductively coupled plasma optical emission spectrometry. |
