Isotopically Labeled Compounds
Medchemexpress LLC Citicoline-d9 (sodium) | 99.8% | 1 MG
Citicoline-d9 (Cytidine diphosphate-choline-d9) sodium is a deuterium-labeled compound and an endogenous intermediate in the synthesis of phosphatidylcholine, a component of cell membranes. It inhibits reactive oxygen species (ROS) and apoptosis and is used in studies related to neurological diseases and hearing loss. Stable heavy isotopes have been incorporated into this drug molecule, primarily as tracers for quantitation during drug development, and deuteration has the potential to affect pharmacokinetic and metabolic profiles.
- Used for neurological disease and hearing loss studies
- Can be used as a tracer
- Functions as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS
- Inhibits reactive oxygen species (ROS) and apoptosis
- Endogenous intermediate in phosphatidylcholine synthesis
- For research use only
