Description

Carbenicillin Phenyl Sodium is a semi-synthetic, β-lactamase-resistant penicillin antibiotic. This compound is valued for its broad-spectrum activity against Gram-negative bacteria, including Pseudomonas aeruginosa, and its stability in the presence of penicillinase enzymes. It is primarily utilized in pharmaceutical research and development, as well as in the production of microbiological culture media for selective growth and antibiotic susceptibility testing.

Application

• Pharmaceutical Intermediate: Serves as a key starting material or intermediate in the synthesis of advanced antibiotic formulations and active pharmaceutical ingredients (APIs).
• Microbiological Research: Used in laboratory settings for studying bacterial resistance mechanisms and the efficacy of β-lactam antibiotics.
• Culture Media Supplement: Incorporated into selective agar and broth media for the isolation and identification of specific bacterial strains in clinical and industrial microbiology.
• Antibiotic Susceptibility Testing: Employed as a reference standard in disc diffusion (Kirby-Bauer) and broth dilution tests to determine bacterial sensitivity.
• Biochemical Studies: Utilized in enzymatic assays to investigate the kinetics and inhibition of β-lactamase enzymes.
