Industrial Applications of 3-Carboxyphenylboronic acid
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Raw material or intermediate for Suzuki-Miyaura cross-coupling reactions | Used to construct biaryl frameworks for active pharmaceutical ingredient (API) synthesis |
| Pharmaceuticals | Synthesis of enzyme inhibitors or receptor antagonists | Participates in targeted drug molecule construction via specific boronic acid group binding |
| Materials | Monomer for conjugated polymer synthesis | Used to synthesize emissive materials (e.g., OLEDs) or electron-transport materials containing fluorene or carbazole units |
| Chemicals | Organic synthesis building block | Serves as a coupling reagent to form carbon–carbon bonds with aryl halides under palladium catalysis |
| Sensing | Probe for saccharide or diol molecular recognition | Enables fluorescent sensor fabrication through reversible covalent binding between boronic acid and diols |
Manufacturing Quality Control of 3-Carboxyphenylboronic acid
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Identification Test | Fourier Transform Infrared Spectroscopy (FT-IR) | Measure the infrared absorption spectrum of the sample and compare it with a reference spectrum to confirm characteristic functional groups of 3-carboxyphenylboronic acid (e.g., B–OH, C=O, O–H absorption peaks) for structural confirmation. |
| Proton Nuclear Magnetic Resonance Spectroscopy (¹H NMR) | Obtain the ¹H NMR spectrum of the sample in a deuterated solvent, and verify molecular structure and purity based on chemical shifts, integration areas, and coupling constants. | |
| Assay | High-Performance Liquid Chromatography (HPLC) | Use a reversed-phase C18 column with an appropriate mixture of water and organic solvent (e.g., methanol or acetonitrile) as the mobile phase, and quantify the main component using a UV detector (typically at 200–260 nm wavelength), offering high sensitivity and good reproducibility. |
| Related Substances / Impurity Check | High-Performance Liquid Chromatography (HPLC) | Similar conditions to the assay, but with optimized gradient elution to separate potential impurities (e.g., unreacted starting materials, by-products, degradation products); impurity content is calculated via peak area normalization or corrected factor methods. |
| Loss on Drying | Thermogravimetric Analysis (TGA) or Constant Temperature Drying | Dry the sample to constant weight at a specified temperature (e.g., 105°C) and measure the mass loss to evaluate moisture and volatile component content. |
| Residue on Ignition | High-Temperature Ashing | Carbonize the sample, then ignite at high temperature (typically 700–800°C), and weigh the residual inorganic matter to control the limit of inorganic impurities. |
| pH Value | pH Meter Method | Prepare an aqueous solution at a specified concentration (e.g., 1% w/v) and measure its acidity using a calibrated pH meter, reflecting the acidic nature of the sample due to the carboxylic acid group. |
| Boron Content | Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) or Titration | ICP-OES accurately determines total boron content; alternatively, boron in the boronic acid group can be indirectly measured via complexation with mannitol followed by titration with a standard NaOH solution. |
| Water Content | Karl Fischer Titration | Utilize Karl Fischer reagent to quantitatively react with water in the sample; moisture content is precisely determined via coulometric or volumetric methods, suitable for trace water analysis. |
