CAS No. 7637-7-2 Boron Fluoride Supplier. Characteristics of Boron Fluoride

Boron trifluoride (BF₃) is a chemical compound that is widely used in the chemical industry, particularly as a catalyst in organic synthesis and as a reagent in various chemical reactions. It has the CAS number 7637-7-2. Here are some key characteristics of boron trifluoride:

Physical Properties:
Appearance: Colorless gas under standard conditions.
Boiling Point: -100.3°C (-148.5°F).
Melting Point: -127.2°C (-196.9°F).
Density: 2.88 g/L at 20°C.
Solubility in Water: Soluble, but it reacts with water to form boric acid and hydrofluoric acid.
Chemical Properties:
Reactivity: Highly reactive, especially with water, alcohols, and other nucleophiles.
Acidity: BF₃ acts as a Lewis acid due to its electron-deficient boron atom.
Toxicity: It can be harmful if inhaled, swallowed, or comes into contact with skin or eyes. It is corrosive and can cause severe burns.
Uses:
Catalysis: Commonly used as a catalyst in Friedel-Crafts reactions and other organic synthesis reactions.
Etching Agent: Used in semiconductor manufacturing for etching silicon dioxide.
Fluorination Reactions: Used in the preparation of fluorinated compounds.
Analytical Chemistry: Used in gas chromatography as a reagent for the derivatization of amines.
When handling boron trifluoride, appropriate safety measures should be taken due to its toxicity and reactivity. This includes using personal protective equipment such as gloves, goggles, and a face shield, working in a well-ventilated area or fume hood, and following all relevant safety guidelines.
