Industrial Applications of CYCLOPENTEN-1-YLBORONIC ACID
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical R&D | Used in the synthesis of active pharmaceutical ingredients (APIs) containing a cyclopentenyl moiety, such as kinase inhibitors and G protein-coupled receptor (GPCR) modulators | Applied in Suzuki-Miyaura cross-coupling reactions as a boronic acid coupling reagent with aryl/heteroaryl halides to construct carbon–carbon bonds under palladium catalysis (e.g., Pd(dppf)Cl₂) |
| Materials Science | Used to prepare organic optoelectronic functional materials featuring a rigid cyclopentenyl backbone for OLED emissive or electron-transport layers | Applied in palladium-catalyzed coupling with electron-deficient aryl halides (e.g., bromocarbazole, dibenzothiophene) to introduce hole-transport or charge-balance units |
| Agrochemical R&D | Used as an intermediate in constructing the cyclopentenyl pharmacophore in novel insecticides or fungicides | Applied in selective coupling with fluorinated aryl chlorides under transition-metal catalysis to optimize compound lipophilicity and target-binding activity |
Manufacturing Quality Control of CYCLOPENTEN-1-YLBORONIC ACID
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main component using reverse-phase HPLC with UV detection at 210-230 nm based on peak area comparison to reference standard. |
| Related Substances | HPLC-UV | Detects and quantifies impurities (e.g., residual starting materials, by-products) using gradient HPLC-UV against qualified reference standards. |
| Residual Solvents | GC-FID | Measures volatile organic solvents (e.g., THF, toluene, methanol) by gas chromatography with flame ionization detection using internal standard calibration. |
| Water Content | Karl Fischer Titration | Determines trace water via coulometric or volumetric titration using iodine generated electrochemically or added stoichiometrically in pyridine-free reagent. |
| Heavy Metals | ICP-MS | Quantifies toxic elements (Pb, Cd, Hg, As, etc.) at sub-pptr levels by inductively coupled plasma mass spectrometry after acid digestion. |
| Chloride Content | Ion Chromatography | Separates and quantifies chloride ions using suppressed conductivity detection after aqueous extraction and filtration. |
| Residue on Ignition | Gravimetric Analysis | Measures non-volatile inorganic residue after high-temperature ashing (500-600 C) and weighing of the cooled crucible. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using calibrated capillary tube method per USP <741>. |
| Optical Rotation | Polarimetry | Measures specific rotation using sodium D-line light to assess chiral purity and detect enantiomeric impurities. |
| pH of Aqueous Suspension | pH Meter | Evaluates acidity/basicity by measuring pH of a defined suspension (e.g., 1% w/v in water) using calibrated electrode. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution of solid particles in suspension using Mie scattering theory and optical detection of diffracted laser light. |
| Bulk Density | Tap Density Tester | Measures mass per unit volume of freely settled and then tapped powder according to USP <616> or ASTM D1895. |
