Medchemexpress LLC Ceftazidime-d5 (GR20263-d5) | 93.7% | 1 MG
Ceftazidime-d5 (GR20263-d5) is a deuterium-labeled antibiotic, specifically a version of Ceftazidime. Ceftazidime exhibits broad-spectrum activity against Gram-positive and Gram-negative aerobic bacteria, including Enterobacteriaceae (even β-lactamase-positive strains), and resists hydrolysis by most β-lactamases. Deuterium-labeled compounds, such as Ceftazidime-d5, are used as tracers for quantitative analysis during drug development, impacting pharmacokinetic and metabolic profiles.
- Deuterium-labeled version of Ceftazidime
- Exhibits broad-spectrum antibiotic activity
- Effective against Gram-positive and Gram-negative aerobic bacteria
- Active against Enterobacteriaceae, including β-lactamase-positive strains
- Resistant to hydrolysis by most β-lactamases
- Useful as a tracer
- Serves as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
