Manufacturing Quality Control of 3-Aminobenzeneboronic acid hemisulfate salt
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantification based on peak area comparison against a certified reference standard using reversed-phase chromatography and UV detection at ~254 nm. |
| Related Substances | HPLC-UV | Separation and detection of impurities (e.g., 3-nitroaniline, 3-bromoaniline, residual solvents) relative to main peak using gradient HPLC-UV. |
| Water Content | Karl Fischer Titration | Electrochemical titration with iodine reagent to determine trace water content based on stoichiometric reaction with iodine and sulfur dioxide. |
| Residual Solvents (e.g., MeOH, EtOAc, THF) | GC-FID | Gas chromatographic separation followed by flame ionization detection; quantified using external calibration standards. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS | Multi-element quantification after acid digestion using inductively coupled plasma mass spectrometry for ultra-trace metal analysis. |
| Sulfate Content | Ion Chromatography | Separation of sulfate anion on an anion-exchange column with suppressed conductivity detection; quantified against sulfate standard. |
| Residue on Ignition | Gravimetric Analysis | Mass loss measured after high-temperature ashing (700-800 C) to determine inorganic ash content. |
| pH of Aqueous Solution | Potentiometric Titration | Measurement of hydrogen ion activity in a 1% w/v aqueous suspension using calibrated pH electrode. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition observed as solid-to-liquid phase change using controlled heating rate and visual or automatic detection. |
| Particle Size Distribution | Laser Diffraction | Analysis of scattered laser light intensity versus angle to calculate volume-based particle size distribution. |
| Bulk Density | ASTM D1895 Method A | Mass per unit volume measured by allowing sample to settle freely into a calibrated cylinder under standardized conditions. |
| Microbial Contamination | Membrane Filtration | Quantitative recovery and cultivation of viable aerobic microorganisms from solution via filtration and agar plate incubation. |
