Product Name:4-Acetoxyazetidinone
English Name:4-Acetoxyazetidinone
CAS No.:76855-69-1
Aliases:4-AA, 4-Acetoxy-2-azetidinone, (3S,4R)-3-[(1R)-1-[(tert-butyldimethylsilyl)oxy]ethyl]-4-acetoxyazetidin-2-one
Molecular Formula:C13H25NO4Si
Physical Properties:White to off-white crystalline powder; readily soluble in dichloromethane, ethyl acetate, methanol and other organic solvents, almost insoluble in water; hygroscopic in air and slowly decomposes upon exposure to moisture; should be stored sealed, protected from light, in a cool and dry place.
Uses:This product is a key intermediate in the synthesis of carbapenem antibiotics such as meropenem, imipenem and biapenem. Through substitution, deprotection and other reactions, it efficiently constructs the carbapenem core with high selectivity and chiral retention. It is also used in the synthesis of other bioactive compounds bearing the β-lactam structure.
Technical Specifications:
Assay: ≥98% (HPLC)
Appearance: white to off-white crystalline powder
Molecular weight: 287.43
Solubility: readily soluble in dichloromethane, ethyl acetate, methanol; almost insoluble in water
Storage: store sealed, protected from light, at 2-8℃ in a dry place
