CAS 109-99-9: Tetrahydrofuran

Description: Tetrahydrofuran (THF) is a colorless, volatile liquid with a distinctive ether-like odor. It is a cyclic ether and serves as an important solvent in organic chemistry due to its ability to dissolve a wide range of polar and nonpolar compounds. THF has a low boiling point and a relatively high vapor pressure, making it useful in various applications, including as a solvent for polymers and in the production of pharmaceuticals. Its chemical structure features a five-membered ring containing four carbon atoms and one oxygen atom, contributing to its reactivity and ability to participate in various chemical reactions, such as polymerization. THF is hygroscopic, meaning it can absorb moisture from the air, which can affect its properties and reactivity. It is also flammable and should be handled with care, using appropriate safety measures to avoid inhalation or skin contact. Additionally, THF can form peroxides upon prolonged exposure to air, necessitating proper storage and handling practices to mitigate risks.
