| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Intermediate in the synthesis of drug molecules, used to construct active pharmaceutical ingredients (APIs) containing phenylboronic acid structures | Forms carbon–carbon bonds via Suzuki–Miyaura coupling with aryl halides under palladium catalysis to synthesize complex drug molecules |
| Agrochemicals | Aromatic boronic acid derivatives for synthesizing novel insecticides or fungicides | Acts as a nucleophilic coupling partner to construct biologically active heterocyclic or aryl structures |
| Materials Science | Precursor for synthesizing organic light-emitting materials or conjugated polymers | Introduces boronic acid functionality via coupling polymerization (e.g., Stille or Suzuki reactions) to tune optoelectronic properties of materials |
| Chemical Research | Functional building block in organic synthesis for investigating reactivity of novel boronic acid derivatives | Used at laboratory scale to screen new catalytic systems or synthesize structurally diverse compound libraries |
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reversed-phase HPLC with UV detection at 254 nm, comparing peak area to reference standard calibration curve. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., residual solvents, synthetic intermediates, degradants) via gradient HPLC-UV against qualified reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, methanol, toluene) by gas chromatography with flame ionization detection using headspace sampling. |
| Water Content | Karl Fischer Titration | Determines trace water by coulometric or volumetric titration based on iodine consumption in pyridine/methanol buffer. |
| Heavy Metals | ICP-OES | Quantifies metals (e.g., Pd, Ni, Fe) after acid digestion by measuring element-specific atomic emission intensities. |
| Chloride Impurity | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction. |
| Sulfated Ash | Gravimetric Analysis | Measures inorganic residue after high-temperature combustion in sulfuric acid medium, followed by weighing of residual ash. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range of solid-to-liquid transition using calibrated capillary tube method per USP <741>. |
| Appearance | Visual Inspection | Assesses physical state, color, and presence of foreign particles under controlled white light against established reference standards. |
| Loss on Drying | Thermogravimetric Analysis | Measures mass loss upon heating under defined conditions (e.g., 105 C, 2 h) to determine volatile content. |
| pH of Aqueous Suspension | pH Meter | Measures hydrogen ion activity in a standardized suspension (e.g., 1% w/v in water) using calibrated pH electrode. |
| Specific Optical Rotation | Polarimetry | Determines chiral purity by measuring angle of plane-polarized light rotation in solution using sodium D-line (589 nm). |
