Manufacturing Quality Control of 3-BROMO-7-NITROINDAZOLE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination using reverse-phase HPLC with UV detection at characteristic wavelength, comparing peak area against certified reference standard. |
| Related Substances | HPLC-UV or UPLC-MS | Separation and detection of structurally related impurities (e.g., isomers, hydrolysis/degradation products) via chromatographic resolution and spectral identification. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents (e.g., dichloromethane, toluene) based on retention time and calibration curves. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying trace water by iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification of toxic metals after acid digestion, using inductively coupled plasma mass spectrometry for sub-ppq sensitivity and isotopic resolution. |
| Residue on Ignition | Gravimetric Analysis | Determination of non-volatile inorganic residue after controlled high-temperature ashing (500–600 °C) and precise weighing of the residual ash. |
| Optical Rotation | [α]D Measurement | Specific rotation determination using a polarimeter at 20 °C and sodium D-line (589 nm) to confirm chiral integrity and enantiomeric identity. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition analysis via controlled heating to identify onset and range of solid-to-liquid phase change, indicating crystallinity and purity. |
| Chloride Impurity | Ion Chromatography (IC) | Separation and quantification of chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| pH of Aqueous Suspension | Potentiometric pH Measurement | Direct pH measurement of a standardized suspension (e.g., 1% w/v in water) using calibrated glass electrode to assess acidic/basic degradation species. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample via light scattering pattern deconvolution to determine D10, D50, D90 values per ISO 13320. |
| Microbial Contamination | Membrane Filtration & Plate Count | Enumeration of aerobic microorganisms following filtration, membrane transfer to appropriate agar media, and colony formation under controlled incubation (USP <61>). |
