FAQ

What are the physical and chemical properties of Methyl diethylborinate (CAS: 7397-46-8)?

Methyl diethylborinate (CAS: 7397-46-8) is a colorless liquid with a molecular weight of approximately 133.15 g/mol. It has a low melting point and is highly soluble in organic solvents but less so in water. Chemically, it is known for its reactivity towards hydrolysis and its ability to act as a boron-containing reagent in various organic syntheses.

How is methyl diethylborinate (CAS: 7397-46-8) typically synthesized?

Methyl diethylborinate (CAS: 7397-46-8) is typically synthesized via the reaction of boron tribromide with a mixture of diethylamine and methylamine. The reaction is exothermic and requires careful temperature control to achieve high yield and selectivity. Commonly, this involves the stepwise addition of the amines to the boron reagent in the presence of a solvent like chlorobenzene.

What industries use methyl diethylborinate (CAS: 7397-46-8)?

Methyl diethylborinate (CAS: 7397-46-8) is widely used in the pharmaceutical industry for the synthesis of boron-containing drugs. It also plays a role in polymer science for the modification of polymer properties and in semiconductor applications for the doping of boron into materials.

What precautions should be taken when handling methyl diethylborinate (CAS: 7397-46-8)?

When handling methyl diethylborinate (CAS: 7397-46-8), it is crucial to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be done in a fume hood to minimize inhalation risk. Spills should be immediately cleaned up with appropriate absorbent materials and proper disposal methods. Always refer to the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
