Molecular Formula: C8H12NNaO5S (or C8H10NNaO5S, depending on specific literature or experimental conditions)
Molecular Weight: 257.24 (or 255.223, also depending on the representation of the molecular formula)
Physical Properties
Appearance: White or off-white crystalline powder
Melting Point: Above 230°C (some literature reports 121-123°C, which may be due to differences in purity or measurement conditions)
Boiling Point: 567.7°C at 760 mmHg
Flash Point: 297.1°C
Solubility: Easily soluble in water, slightly soluble in ethyl acetate, very slightly soluble in ethanol (96%), and also easily soluble in dilute acid.
Chemical Properties
Category: β-Lactamase Inhibitor
Characteristics: Sulbactam Sodium is an irreversible competitive β-lactamase inhibitor that inhibits β-lactamases produced by both Gram-positive and Gram-negative bacteria (except Pseudomonas aeruginosa). After an irreversible reaction with the enzyme, the enzyme is inactivated, and its activity cannot be restored even after the inhibitor is removed.
