Oxacillin sodium salt
Oxacillin sodium salt (CAS: 1173-88-2) is a semi-synthetic penicillinase-resistant antibiotic with the molecular formula C19H18N3NaO5S and a molecular weight of 423.42 g/mol. It functions by interfering with bacterial cell wall synthesis. Oxacillin sodium salt is primarily utilised in research settings to investigate mechanisms of penicillinase resistance, antimicrobial susceptibility, and bacterial autolysins. Its properties make it a valuable reagent for microbiological studies.

Research into Penicillinase Resistance
Oxacillin sodium salt serves as a critical tool for studying the mechanisms by which bacteria develop resistance to penicillinase enzymes. This research aids in understanding antibiotic resistance patterns.
Antimicrobial Susceptibility Testing
This compound is employed in laboratory settings to assess the susceptibility of various bacterial strains to oxacillin. Such studies are fundamental to developing effective treatment strategies against infections.
Investigation of Bacterial Autolysins
Oxacillin sodium salt has been used in research to explore the role and function of bacterial autolysins, enzymes involved in cell wall remodelling and turnover, which are crucial for bacterial growth and division.
