CAS 18531-99-2: (-)-Binol

Description:(-)-Binol, also known as 1,1'-bi-2-naphthol, is a chiral organic compound characterized by its two naphthalene rings connected by a single bond, with hydroxyl groups (-OH) positioned at the 1 and 1' positions. This compound is notable for its ability to act as a chiral ligand in asymmetric synthesis, making it valuable in various chemical reactions, particularly in catalysis. (-)-Binol exhibits strong optical activity due to its chiral nature, allowing it to rotate plane-polarized light. It is typically a white to off-white crystalline solid and is soluble in organic solvents such as ethanol and acetone, but less soluble in water. The compound's stereochemistry plays a crucial role in its reactivity and interactions, making it a key player in the development of enantioselective processes in organic chemistry. Additionally, (-)-Binol can undergo various transformations, including oxidation and esterification, further expanding its utility in synthetic applications.
