Isotopically Labeled Compounds
Medchemexpress LLC DM4-d6 | 99.1% | 786.40 | 1 MG
DM4-d6 is deuterium labeled DM4, an antitubulin agent that inhibits cell division and can be used in the preparation of antibody agent conjugate.
- 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 of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process.
- Deuteration has potential to affect the pharmacokinetic and metabolic profiles of drugs.
