Industrial Applications of 2-Aminophenylboronic acid
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Synthesis of antitumor agents (e.g., bortezomib analogues) and proteasome inhibitor intermediates | Palladium-catalyzed cross-coupling reactions (e.g., Suzuki-Miyaura coupling) to construct aryl-heteroaryl bonds; subsequent conversion to target active molecules via diazotization, hydrolysis, and related steps |
| Agrochemicals | Key structural motif in novel insecticides and fungicides | Serves as a boronic acid-functionalized arene precursor for heterocycle construction and side-chain modification to optimize biological activity and metabolic stability |
| Materials Science | Synthetic intermediate for hole-transport layers or emissive-layer dopants in organic light-emitting diodes (OLEDs) | Suzuki coupling used to introduce electron-donating or electron-withdrawing groups, enabling HOMO/LUMO energy-level tuning; final film formation performed via vacuum thermal evaporation or solution spin-coating |
| Chemical Reagents | Boronic acid recognition moiety carrier for highly selective fluorescent probes (e.g., for glucose or hydrogen peroxide detection) | Cooperates with ortho-amino groups to form stable five-membered boronate ester complexes, enhancing binding specificity and response sensitivity toward cis-diol analytes |
Manufacturing Quality Control of 2-Aminophenylboronic acid
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantitative determination 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 quantification of structurally similar impurities (e.g., aniline, nitrobenzene, boronic acid esters) using gradient HPLC with UV detection. |
| Residual Solvents | GC-FID | Identification and quantification of volatile organic solvents (e.g., THF, methanol, toluene) by gas chromatography with flame ionization detection. |
| Water Content | Karl Fischer Titration | Volumetric or coulometric titration based on the stoichiometric reaction of iodine with water in a pyridine-methanol buffer system. |
| Heavy Metals (as Pb) | ICP-OES | Multi-element quantification of toxic metals (Pb, Cd, Hg, As) after acid digestion, using inductively coupled plasma optical emission spectroscopy. |
| Chloride Impurity | Ion Chromatography | Separation and quantification of chloride ions using anion-exchange column with suppressed conductivity detection. |
| Sulfated Ash | Gravimetric Analysis | Residue mass measurement after high-temperature incineration (500–600 C) of sample followed by sulfuric acid treatment and ignition. |
| Melting Point | Capillary Melting Point Apparatus | Thermal transition detection by observing solid-to-liquid phase change in a capillary tube under controlled heating rate. |
| Appearance | Visual Inspection | Assessment of physical state, color, and presence of foreign particles under standardized white-light illumination against a white background. |
| pH of Aqueous Suspension | pH Meter | Measurement of hydrogen ion activity in a 1% (w/v) suspension in purified water using a calibrated pH electrode. |
| Particle Size Distribution | Laser Diffraction | Determination of size distribution by analyzing angular scattering pattern of laser light passing through a dispersed sample in liquid medium. |
| Bulk Density | Graduated Cylinder Method | Mass per unit volume determined by gently pouring sample into a calibrated cylinder and measuring settled volume without compaction. |
