In the realm of fine chemicals, understanding the intrinsic properties of a substance is the first step toward harnessing its full potential. Boron Trifluoride Tetrahydrofuran Complex, known by its CAS number 462-34-0, is a compound of significant interest due to its versatile applications as a Lewis acid. A thorough examination of its chemical and physical characteristics is essential for researchers and procurement managers to ensure optimal utilization and safe handling.

Firstly, let's consider its appearance. Boron Trifluoride Tetrahydrofuran Complex is typically described as a colorless to pale yellow liquid. This liquid form is a significant advantage over anhydrous boron trifluoride gas, offering greater ease of handling, measurement, and addition in chemical reactions. The consistent appearance from a reputable manufacturer indicates a high degree of purity and quality control.

Chemically, the complex is an adduct formed between boron trifluoride (BF3) and tetrahydrofuran (THF). BF3 itself is a strong Lewis acid, meaning it readily accepts an electron pair. When complexed with THF, a cyclic ether, the reactivity of BF3 is moderated, making it more stable and less volatile. This complex retains its Lewis acidity, enabling it to catalyze a wide array of organic reactions. Its typical purity, often around 47-50% assay by titration, makes it suitable for most synthetic applications. For those looking to buy, understanding these specifications is crucial.

Key physical properties include its melting point, which is in the range of 11-13 °C, and its boiling point, approximately 180 °C. Its density is around 1.268 g/mL at 25 °C. These parameters are important for storage and reaction condition calculations. The compound is generally miscible with organic solvents like dimethyl formamide, though it reacts with water, undergoing hydrolysis. This sensitivity to moisture necessitates careful storage, typically at room temperature and in tightly sealed containers. Suppliers often include information on these handling requirements.

Furthermore, the inclusion of a small percentage of sulfur dioxide (>0.5%) as a peroxide formation suppressor is a notable characteristic. This additive enhances the shelf life and safety of the complex by preventing the accumulation of potentially hazardous peroxides, a common issue with ethers. This detail is particularly important for users who require long-term stability or are involved in large-scale operations.

For industries relying on this compound, securing a consistent supply from trusted manufacturers in China is a common strategy. Understanding these properties allows procurement specialists to effectively source and implement Boron Trifluoride Tetrahydrofuran Complex in their processes, whether for organic synthesis, polymerization, or other chemical applications. Inquiring about specific product specifications and pricing is a vital step in the procurement process.

In essence, the Boron Trifluoride Tetrahydrofuran Complex (CAS 462-34-0) is a well-characterized and valuable chemical reagent. Its unique combination of Lewis acidity, liquid state, and enhanced stability makes it an excellent choice for a variety of chemical applications. Ensuring you buy from a reputable supplier guarantees that you receive a product that meets these essential chemical and physical property requirements for your critical processes.
