It functions as a potent -lactamase inhibitor used in combination with -lactam antibiotics like amoxicillin to overcome bacterial resistance serving as a pharmaceutical reference standard and active ingredient in formulations targeting infections caused by -lactamase-producing bacteria.

Lithium clavulanate irreversibly binds to and inhibits -lactamase enzymes produced by resistant bacteria protecting partner antibiotics from degradation and restoring their bactericidal activity against pathogens like Staphylococcus aureus and certain E

Lithium clavulanate is the lithium salt of clavulanic acid with the molecular formula CHLiNO CAS number 61177-44-4 and molecular weight of 205.09 gmol appearing as a white to off-white solid with a bicyclic -lactam structure that includes a (2R3Z5R)-3-(2-hydroxyethylidene)-7-oxo-4-oxa-1-azabicyclo[3.2.0]heptane-2-carboxylate core.
