Medchemexpress LLC Thiamphenicol-d3-1 | 1217723-41-5 | 99.0% | 1 MG
Thiamphenicol-d3-1 is a deuterium-labeled form of Thiamphenicol, a methyl-sulfonyl derivative of Chloramphenicol. It acts as a broad-spectrum antimicrobial antibiotic by binding to the 50S ribosomal subunit, inhibiting protein synthesis and resulting in a bacteriostatic effect against Gram-negative, Gram-positive aerobic, and anaerobic bacteria. Deuteration can influence the pharmacokinetic and metabolic profiles of drugs, and stable heavy isotopes are incorporated for quantitation during drug development.
- Used as a tracer
- Functions as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
- Exhibits broad-spectrum antimicrobial activity
- Inhibits protein synthesis by binding to the 50S ribosomal subunit
- Effective against Gram-negative, Gram-positive aerobic, and anaerobic bacteria
