Cephalosporin C sodium salt is primarily used in the pharmaceutical industry as a key intermediate in the production of various cephalosporin antibiotics. These antibiotics are widely employed to treat bacterial infections, including respiratory tract infections, skin infections, urinary tract infections, and more severe conditions like sepsis. Its role in antibiotic synthesis makes it critical for developing effective treatments against both Gram-positive and Gram-negative bacteria. Additionally, it serves as a starting material for further chemical modifications to enhance the efficacy, stability, and spectrum of activity of derived antibiotics.
