Industrial Applications of 2-Isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
| Industry | Application | Process |
|---|---|---|
| Pharmaceutical Industry | Used as a boronate reagent in asymmetric synthesis for Suzuki cross-coupling to construct C–C bonds | Undergoes cross-coupling with aryl or alkenyl halides in the presence of a palladium catalyst |
| Organic Synthesis | Used as a protecting group for boronic acids to enhance stability and reaction selectivity of boronic acid derivatives | Prepared via transesterification of pinacol boronic acid with isopropanol under acidic conditions, or directly via esterification with boronic acid |
| Materials Science | Used as a boron-doping precursor in organic light-emitting diodes (OLEDs) and conjugated polymers | Releases boron species during pyrolysis or chemical vapor deposition (CVD) to achieve atomic boron doping |
Manufacturing Quality Control of 2-Isopropoxy-4,4,5,5-tetramethyl-1,3,2-dioxaborolane
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Purity | Gas Chromatography (GC) | Capillary column separation with FID detector for quantitative analysis of main component content, evaluating sample purity. Suitable for volatile organic borate esters. |
| Impurity Content | High-Performance Liquid Chromatography (HPLC) | Using reversed-phase chromatographic columns with UV or ELSD detectors to separate and quantify trace organic impurities (e.g., raw material residues, by-products). |
| Moisture Content | Karl Fischer Titration | Utilizes the quantitative reaction between iodine and sulfur dioxide in a methanol/pyridine system with water, accurately determining trace moisture in samples, avoiding hydrolysis of borate esters. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | Volatilized solvents are released from heated samples and detected by GC-FID or MS, quantifying common process residual solvents (e.g., toluene, ethyl acetate). |
| Structure Confirmation | Nuclear Magnetic Resonance Spectroscopy (NMR) | ¹H-NMR and ¹³C-NMR are used to analyze molecular structure characteristic peaks (e.g., pinacol group, isopropyl group, B-O bond signals) to confirm the target compound's structure. |
| Elemental Composition | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Determines boron content to assist in verifying the molecular formula; it can also detect metal catalyst residues (e.g., Pd, Ni). |
| Melting Point / Boiling Point | Capillary Melting Point Apparatus / Distillation | Measures physical constants as a preliminary identification basis; isopropyl pinacol borate is typically a liquid, and its boiling point or refractive index can be measured for further confirmation. |
| Appearance and Color | Visual Color Comparison | Observes whether the sample is clear and transparent, free of suspended particles or abnormal color, meeting pharmacopoeia or internal control standards. |
| pH Value (in aqueous solution) | pH Meter Measurement | The pH is measured after dissolving the sample in an appropriate solvent/buffer solution, assessing its acid-base stability and potential hydrolysis tendency. |
| Thermal Stability | Differential Scanning Calorimetry (DSC) | Measures endothermic/exothermic behavior under programmed temperature control to evaluate thermal decomposition temperature and storage stability. |
