Manufacturing Quality Control of 4-BROMO-1-METHYL-1H-INDAZOLE
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, based on peak area comparison against reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies structurally related impurities using gradient HPLC-UV; identification relies on retention time matching and relative response factors. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., methanol, acetone, ethyl acetate) by headspace GC with flame ionization detection using calibrated standards. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration with iodine-based reagent, where water reacts stoichiometrically to generate endpoint current or color change. |
| Heavy Metals | ICP-MS | Quantifies trace metals (Pb, Cd, Hg, As, etc.) after acid digestion using inductively coupled plasma mass spectrometry for multi-element detection at sub-ppt levels. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column with suppressed conductivity detection, calibrated against sodium chloride standards. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after controlled combustion at 700-800 C followed by sulfuric acid treatment and final weighing. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light source in solution; indicates chiral purity and absence of racemization. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed sample via light scattering pattern to determine D10, D50, D90 values per ISO 13320. |
| Bulk Density | ASTM D1895 Method A | Measures mass per unit volume of freely settled powder in a standardized cylinder using calibrated balance and volumetric measure. |
| Microbial Limits | Membrane Filtration | Quantifies aerobic microorganisms and detects specified pathogens (e.g., E. coli, S. aureus) by filtration, culture on selective media, and colony enumeration. |
