Manufacturing Quality Control of 7-Nitroindazole
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification by comparison of peak area against a certified reference standard using reversed-phase chromatography and UV detection at 254 nm. |
| Related Substances | HPLC-UV | Separation and quantification of structurally related impurities using gradient HPLC with UV detection and relative response factors. |
| Residual Solvents | GC-FID | Headspace gas chromatography with flame ionization detection to quantify volatile organic solvents based on retention time and peak area. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration using iodine-based reagent to determine water content via stoichiometric reaction. |
| Heavy Metals | ICP-OES | Multi-element quantification of toxic metals (e.g., Pb, Cd, Hg, As) after acid digestion, using plasma emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column and conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Incineration at 700-800 C followed by weighing of inorganic residue after treatment with sulfuric acid. |
| Melting Point | Capillary Melting Point Apparatus | Determination of temperature range at which solid transitions to liquid, measured using calibrated capillary apparatus. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under controlled white light and against standard references. |
| Particle Size Distribution | Laser Diffraction | Analysis of particle size distribution based on angular scattering pattern of laser beam passing through dispersed sample. |
| Loss on Drying | Thermogravimetric Analysis | Measurement of mass loss upon heating at 105 C for 2 hours to determine volatile content excluding water. |
| Specific Optical Rotation | Polarimetry | Measurement of rotation angle of plane-polarized light induced by chiral molecules in solution at specified concentration and wavelength. |
