Cas no 221093-33-0 (2-Hydroxy-17β-estradiol-16,16,17-d5)

2-Hydroxy-17β-estradiol-16,16,17-d5 is a deuterium-labeled analog of 2-hydroxyestradiol, a key metabolite of estradiol. The incorporation of five deuterium atoms at the 16,16,17 positions enhances its stability, making it particularly useful for quantitative mass spectrometry and metabolic studies. This labeled compound serves as an internal standard for accurate quantification of endogenous 2-hydroxyestradiol in biological matrices, minimizing interference from isotopic effects. Its high isotopic purity and well-defined structure ensure reliable performance in pharmacokinetic and endocrine research applications. The compound is valuable for investigating estrogen metabolism pathways, oxidative stress mechanisms, and hormone-related disease models.
