17β-Estradiol-d3 17-Acetate (CAS 1743-60-8 unlabeled)

17β-Estradiol-d3 17-Acetate is a deuterium-labeled derivative of estradiol acetate, a naturally occurring estrogen modified for research purposes. This compound integrates deuterium atoms at specific positions, making it a stable isotope-labeled analogue. Such labeling enhances its detection and quantification in analytical research, particularly using mass spectrometry, due to the distinct mass differences imparted by the deuterium atoms. The acetate group at the 17 position modifies its solubility and reactivity, facilitating its use in various experimental applications. In biochemical and cellular studies, this compound serves as a critical tool for tracing the metabolic pathways of estrogens, understanding estrogen receptor interactions, and elucidating the role of estrogens in cell signaling processes. By allowing precise tracking without altering the biological activity of the parent compound, 17β-Estradiol-d3 17-Acetate becomes indispensable in research focused on the molecular mechanisms of estrogen action and the intricate roles of hormones in biological systems.
