Manufacturing Quality Control of 7-BROMO-5-NITRO-1H-INDAZOLE
| 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 against a certified reference standard. |
| Related Substances | HPLC-UV or UPLC-MS | Separation and identification/quantification of structurally related impurities (e.g., regioisomers, des-bromo, nitro-reduction products) using gradient elution and retention time/mass matching. |
| Residual Solvents | GC-FID or GC-MS | Headspace GC analysis with flame ionization detection to quantify common solvents (e.g., DMF, ethyl acetate, methanol) based on calibrated external/internal standards. |
| Water Content | Karl Fischer Titration (Coulometric) | Electrochemical titration quantifying water via iodine generation and stoichiometric reaction with water in anhydrous methanol-based reagent. |
| Inorganic Residues (Sulfated Ash) | Gravimetric Analysis | High-temperature incineration followed by sulfuric acid treatment and weighing of residual inorganic salts as sulfate ash. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after microwave-assisted acid digestion, using isotopic dilution or external calibration for trace-level detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of dry or wet dispersed sample via Mie scattering theory to determine D10, D50, D90 values across 0.1–2000 µm range. |
| Melting Point | Differential Scanning Calorimetry (DSC) | Thermal transition measurement detecting endothermic melting peak onset and range under controlled nitrogen purge. |
| Chloride Impurity | Ion Chromatography (IC) with Conductivity Detection | Separation of chloride ions on an anion-exchange column and quantification via conductivity response relative to chloride standard calibration. |
| Optical Rotation | [α]D Measurement | Polarimetric determination of specific rotation at 589 nm (Na D-line) in specified solvent/concentration to assess chiral purity (if applicable; note compound is achiral but method included for batch consistency screening). |
