CAS 4737-50-2

B-Pentylboronic acid

Description:

B-Pentylboronic acid, with the CAS number 4737-50-2, is an organoboron compound characterized by the presence of a boronic acid functional group attached to a pentyl chain. This compound typically appears as a colorless to pale yellow liquid or solid, depending on its purity and form. It is known for its ability to form reversible covalent bonds with diols, making it valuable in various applications, particularly in organic synthesis and medicinal chemistry. B-Pentylboronic acid is soluble in polar organic solvents, which enhances its utility in chemical reactions. Its reactivity is primarily attributed to the boron atom, which can participate in nucleophilic attacks and facilitate cross-coupling reactions, such as Suzuki-Miyaura coupling, to form carbon-carbon bonds. Additionally, the presence of the pentyl group can influence the compound's lipophilicity and biological activity. Safety precautions should be taken when handling this compound, as boronic acids can be irritants and may pose environmental hazards if not disposed of properly.
