Indoleacetic Acid-d4 (CAS 76937-77-4)

Indoleacetic Acid-d4 is a stable isotope-labeled version of indoleacetic acid, where four hydrogen atoms are replaced with deuterium, the stable isotope of hydrogen. This labeling enhances the compound′s detection and measurement in various analytical techniques, particularly mass spectrometry, due to the increase in mass and the distinctive mass spectral signatures provided by the deuterium atoms. Indoleacetic acid (IAA) is a naturally occurring plant hormone in the auxin family, which plays a crucial role in regulating plant growth and development. The labeled version, Indoleacetic Acid-d4, is used extensively in research to study the transport, metabolism, and biological effects of IAA in plants without altering its biochemical behavior. This is particularly useful for tracing the pathways of IAA degradation and synthesis within plant systems, helping to better understand its role in processes like cell elongation, bud formation, and root development. The use of a stable isotope-labeled version ensures precise and reliable data in experiments focusing on the dynamic roles of plant hormones.
