Description
7-Aminocephalosporanic acid is the core chemical structure for the synthesis of cephalosporin antibiotics, is a potent β-lactamase inhibitor.
7beta-aminocephalosporanic acid is the alpha,beta-unsaturated monocarboxylic acid that is the active nucleus for the synthesis of cephalosporins and intermediates. It derives from a cephalosporanic acid. It is a tautomer of a 7beta-aminocephalosporanic acid zwitterion.
