Isotopically Labeled Compounds
Medchemexpress LLC DL-Alanine-d3 | 53795-94-1 | 250 MG
This product is a deuterium-labeled form of DL-alanine, an amino acid that exists as a racemic mixture of its L- and D- forms. It acts as both a reducing and capping agent, particularly with silver nitrate aqueous solutions for nanoparticle production. Additionally, it is useful in the study of transition metal chelation, such as with copper (II), zinc (II), and cadmium (II). It is also recognized as a sweetener, alongside substances like glycine and sodium saccharin, and plays a significant role in the glucose-alanine cycle occurring between tissues and the liver.
- It can be used as a tracer.
- It can serve as an internal standard for quantitative analysis through techniques like NMR, GC-MS, or LC-MS.
- Stable heavy isotopes have been incorporated into drug molecules for quantitation during drug development.
- Deuteration may impact the pharmacokinetic and metabolic profiles of drugs.
