| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Boronic acid compounds for constructing drug molecule scaffolds containing phenyl rings via Suzuki coupling reactions | Used as arylboronic acid derivatives in palladium-catalyzed cross-coupling reactions to synthesize potential anticancer and anti-inflammatory active compounds |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component by UV absorption at specific wavelength using reverse-phase chromatography with external standard calibration. |
| Related Substances | HPLC-UV | Detects and quantifies structurally similar impurities using gradient elution and UV detection against reference standards. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents by gas chromatography with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Measures water via coulometric or volumetric titration based on iodine consumption in pyridine-methanol buffer. |
| Heavy Metals | ICP-OES | Determines total heavy metal content (e.g., Pb, Cd, Ni) by atomic emission spectroscopy after acid digestion. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using anion-exchange column and suppressed conductivity detection. |
| Residual Boron | ICP-OES | Quantifies total boron content after microwave-assisted acid digestion and spectral analysis at characteristic emission lines. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using controlled heating and visual observation. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light and against standard references. |
| Loss on Drying | Gravimetric Analysis | Measures mass loss after drying under specified temperature and vacuum conditions to determine volatile content. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light to confirm chiral integrity and absence of racemization. |
| pH of Aqueous Suspension | pH Meter | Determines acidity/basicity of a standardized suspension in water using calibrated electrode and temperature compensation. |
