Manufacturing Quality Control of 3-BROMO-5-CARBOXYBENZENEBORONIC ACID 97
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., starting materials, isomers, de-boronated or brominated by-products) via gradient HPLC separation and UV detection. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) using gas chromatography with flame ionization detection and internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine generation and stoichiometric reaction with water. |
| Heavy Metals | ICP-MS | Quantifies elemental impurities (e.g., Pd, Ni, Fe, Cu) using inductively coupled plasma mass spectrometry with isotope dilution or external calibration. |
| Residual Palladium | ICP-OES | Measures palladium from Suzuki coupling catalyst residue using inductively coupled plasma optical emission spectroscopy. |
| Acid Value | Acid-Base Titration | Determines carboxylic acid content by titration with standardized NaOH solution using phenolphthalein indicator or potentiometric endpoint. |
| Boron Content | ICP-OES | Quantifies total boron by measuring boron spectral line intensity after acid digestion and nebulization into plasma. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary apparatus under controlled heating rate. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles or discoloration against standard reference under controlled lighting. |
| Loss on Drying | Gravimetric Analysis | Measures volatile loss by weighing sample before and after drying at specified temperature and vacuum/time conditions. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using angular scattering pattern of laser beam and Mie theory calculation. |
