Medchemexpress LLC D-Xylulose-1-¹³C | 131771-46-5 | 99.2% | 151.12 | 10 MG

D-Xylulose-1-¹³C is a ¹³C labeled form of D-Xylulose, which serves as a precursor to the pentiol D-arabi. Stable heavy isotopes, such as those of hydrogen, carbon, and other elements, are frequently integrated into drug molecules to act as tracers for quantitative analysis during drug development. Deuteration, in particular, has garnered attention due to its potential to influence the pharmacokinetic and metabolic profiles of drugs.

Can be utilized as a tracer.
Suitable for use as an internal standard for quantitative analysis.
Supports analysis by techniques such as NMR, GC-MS, or LC-MS.
Incorporates stable heavy isotopes.
