Used as an intermediate in pharmaceutical synthesis, particularly in the development of beta-lactam antibiotics. Its structure supports the construction of complex molecules by providing a protected azetidine ring, which is key in creating biologically active compounds. The tert-butyloxycarbonyl (Boc) group allows for selective protection of nitrogen, enabling controlled reactions in multi-step syntheses. The benzoic acid moiety can be further modified to link with other pharmacophores, making it valuable in medicinal chemistry for designing drug candidates with improved stability and binding properties.
