(R)-(3-hydroxy-2,3-dimethylbutyl)triphenylphosphonium iodide is a chiral phosphonium salt synthesized via quaternization of triphenylphosphine with (R)-3-bromo-2,3-dimethylbutane. Molecular Formula: C21H24OPI; CAS No.: 126759-88-0. This reagent serves as a critical intermediate for asymmetric synthesis in pharmaceutical manufacturing.
Store under inert atmosphere at -20°C to prevent decomposition. Handle with appropriate PPE due to potential irritancy; avoid inhalation or skin contact during industrial processing.
