Description

Carbenicillin Disodium is a broad-spectrum, semi-synthetic penicillin antibiotic derived from the penicillin nucleus. This compound is valued for its activity against a wide range of Gram-negative bacteria, including many Pseudomonas aeruginosa strains, making it a critical agent in research and development. It is primarily utilized in the fields of pharmaceutical research, microbiology, and as a selective agent in cell culture media. Our high-purity grade ensures reliable and reproducible results for your critical applications.

Application

• Pharmaceutical Research & Development: Used as a key intermediate or reference standard in the development of antibacterial agents and studies on antibiotic resistance mechanisms.
• Microbiological Studies: Employed as a selective agent in culture media for the isolation and study of specific bacterial strains, particularly in academic and industrial laboratories.
• Cell Culture Applications: Serves as an antibiotic supplement in mammalian cell culture to prevent bacterial contamination, especially where its specific antibacterial profile is required.
• Biochemical Research: Utilized in enzymatic studies and biochemical assays investigating β-lactamase activity and penicillin-binding proteins.
