Isotopically Labeled Compounds
Medchemexpress LLC Thymidine-13C | 478511-06-7 | 243.22 | 5 MG
Thymidine-13C is the 13C labeled Thymidine. It is a specific precursor of deoxyribonucleic acid and functions as a cell synchronizing agent. Thymidine is also a DNA synthesis inhibitor capable of arresting cells at the G1/S boundary, before DNA replication.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Stable heavy isotopes are incorporated into drug molecules for quantitation during drug development.
- Deuteration has the potential to influence the pharmacokinetic and metabolic profiles of drugs.
