| Organic synthesis | Serves as an isoprenyl (3-methyl-2-butenyl) reagent for introducing isoprenyl groups onto aromatic or heteroaromatic rings. | Suzuki-Miyaura cross-coupling reaction |
| Fragrances and flavors | Used to synthesize isoprenyl side chains found in natural products, enabling construction of complex fragrance molecules. | Suzuki-Miyaura cross-coupling reaction |
Manufacturing Quality Control of 2,2-Dimethylethenylboronic acid pinacol ester
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Assay (Purity) | HPLC-UV | Quantifies main compound using reversed-phase HPLC with UV detection at 210-220 nm based on peak area comparison against reference standard. |
| Residual Solvents | GC-FID | Separates and quantifies volatile organic solvents (e.g., THF, toluene, methanol) using capillary GC with flame ionization detection. |
| Water Content | Karl Fischer Titration | Determines water by coulometric or volumetric titration where iodine reacts stoichiometrically with water in a pyridine-methanol buffer. |
| Heavy Metals | ICP-MS | Measures trace metal impurities (e.g., Pd, Ni, Fe) after acid digestion by detecting elemental mass-to-charge ratios with high sensitivity. |
| Residual Boron | ICP-OES | Quantifies total boron content via atomic emission from excited boron atoms in argon plasma after sample mineralization. |
| Chloride Impurity | Ion Chromatography | Separates and detects chloride ions using anion-exchange column and suppressed conductivity detection. |
| Related Substances | HPLC-DAD | Identifies and quantifies structurally related impurities (e.g., hydrolysis products, isomers) using diode array detection for spectral confirmation. |
| Acid Value | Acid-Base Titration | Measures free carboxylic acid impurities by titration with standardized NaOH solution using phenolphthalein indicator. |
| Residue on Ignition | Gravimetric Analysis | Determines non-volatile inorganic residue by high-temperature ashing followed by precise weighing of the remaining solids. |
| Melting Point | Capillary Melting Point Apparatus | Determines temperature range at which solid transitions to liquid using controlled heating and visual observation. |
| Specific Optical Rotation | Polarimetry | Measures chiral purity by determining rotation angle of plane-polarized light passing through a solution of the compound. |
| Particle Size Distribution | Laser Diffraction | Analyzes dry or wet dispersed particles by measuring angular variation in intensity of scattered laser light. |
