Reference hazards: Published SDS describe a combustible, corrosive liquid with harmful inhalation effects and organ damage from prolonged or repeated exposure. Skin and eye contact can cause severe burns or injury. Confirm the complete hazard classification and label in the supplied-grade SDS.
Handling and storage: Use appropriate ventilation, ignition controls, and protective equipment. Keep suitable containers tightly closed in a cool, dry, well-ventilated location. Prevent exposure to water or moist air and follow the current SDS for storage conditions and incompatibilities.
Transport reference: Current published SDS list UN 3265, CORROSIVE LIQUID, ACIDIC, ORGANIC, N.O.S. (boron trifluoride tetrahydrofuran complex), Class 8, Packing Group II. Confirm the classification and shipping documents for the actual supplied formulation, packaging, and transport mode.
Documentation before ordering: Request the current product SDS, relevant batch COA, and applicable packaging and dangerous goods transport information. Include any stabilizer or additional analytical requirements in the specification review.
Boron Trifluoride Tetrahydrofuran Complex CAS 462-34-0
Boron Trifluoride Tetrahydrofuran Complex CAS 462-34-0 from Aure Chemical
Boron trifluoride tetrahydrofuran complex, commonly called BF₃-THF or BF₃·THF (CAS 462-34-0), is a coordination adduct of boron trifluoride with tetrahydrofuran. It is used as a Lewis acid reagent in selected organic synthesis and polymerization processes. Aure Chemical supports China chemical sourcing, product specification review, quality documentation, and export coordination for this complex.
The reference commercial specification includes a BF₃ component assay of 47.0–49.0%, together with moisture, sulfate, appearance, and a reported physical property at 20 °C. The BF₃ assay describes the BF₃ component of the complex; the COA does not provide a separate overall complex purity assay.

| Chemical Structure | BF₃·THF coordination adduct: the oxygen atom of tetrahydrofuran donates an electron pair to boron in BF₃. |
The melting point is general reference information from a published SDS and is not a measurement from the reference COA. Confirm physical properties, packaging, and handling requirements for the actual supplied formulation.
Reference Quality Analysis
The following quality parameters provide a technical reference for evaluating boron trifluoride tetrahydrofuran complex, covering BF₃ assay, moisture, sulfate, appearance, and the physical property reported at 20 °C. The results represent one reference batch.
| Test Item | Reported Specification | Reference Result |
|---|---|---|
| Appearance | Light yellow to brown liquid | Light yellow liquid |
| BF₃ assay | 47.0–49.0% | 48.08% |
| Moisture | ≤0.3% | 0.0874% |
| Sulfate (SO₄²⁻) | ≤0.035% | <0.01% |
| Specific gravity at 20 °C (COA wording) | 1.260 ± 0.005 g/cm³ | 1.262 g/cm³ |
The COA labels the 20 °C property as “specific gravity” while giving g/cm³, a density unit. The original values and unit are retained here. Confirm whether the intended parameter is density or dimensionless relative density before agreeing a purchase specification.
Analytical methods and the basis of the reported percentages are not stated in the COA. Any stabilizer identity, concentration, or additional impurity requirements should be confirmed separately.
These analytical values support preliminary technical evaluation and do not establish guaranteed specifications for every shipment. Confirm the applicable BF₃ assay range, moisture and sulfate limits, physical property requirements, and relevant batch-specific Certificate of Analysis (COA) with Aure Chemical before ordering.
Main Functions and Applications of Boron Trifluoride Tetrahydrofuran Complex
Lewis acid reagent in organic synthesis: Used in selected organic transformations requiring Lewis acid activation. Reaction suitability depends on the substrate, solvent, and complete reagent system. Review BF₃ assay, moisture, and sulfate requirements against the intended process.
Fine chemical and pharmaceutical intermediate synthesis: BF₃-THF has been used as a reagent in routes to biologically active molecules and complex natural products. Qualification for an industrial route requires process-specific impurity review and reaction testing.
Polymerization and materials research: Used in selected polymerization initiator systems and research involving BF₃-containing polymer electrolytes. Monomer compatibility, catalyst formulation, and impurity tolerance must be evaluated for the particular application.
The reference COA reports chemical quality parameters. Catalytic activity, reaction selectivity, and suitability for a particular downstream application require separate evaluation.
