Displaying 2 results of Azelaic Acid Stable Isotopes Azelaic acid stable isotopes are non-radioactive forms of azelaic acid that are used in various research applications. These isotopes are chemically identical to naturally occurring azelaic acid, but have a different number of neutrons in their nuclei, resulting in different atomic weights. Azelaic acid stable isotopes are useful in studies of metabolic pathways, drug development, and environmental monitoring. They are also used in tracer studies to determine the fate of azelaic acid in biological and environmental systems.
