| Hazard Information | Back Directory | [Uses]
2-Azetidinone was used in synthesis of optically pure densely functionalized γ-lactams. | [Definition]
ChEBI: An unsubstituted beta-lactam compound. | [General Description]
2-Azetidinone is an unsubstituted four membered lactam. 2-Azetidinone is the fundamental building block of β-lactam antibiotics. X-ray photoelectron spectra of 2-azetidinone was investigated. 2-Azetidinone undergoes hydrolysis with aqueous alkali to yield β-alanine. |
