5β,19-Cycloandrostane-3,17-dione-d2

5β,19-Cycloandrostane-3,17-dione-d2 is a deuterated derivative of the steroid hormone androstenedione. It is a commonly used compound in research and analytical laboratories, particularly in the field of steroid chemistry, due to its ability to serve as a stable internal standard for quantitative analysis of androstenedione in biological samples. The compound is typically used in gas chromatography-mass spectrometry (GC-MS) analysis, where it is added to samples in known quantities before analysis. This allows for precise quantification of androstenedione levels in biological samples such as blood, urine, and saliva. 5β,19-Cycloandrostane-3,17-dione-d2 contains two deuterium atoms, which replace two hydrogen atoms in the molecule. This substitution makes it easy to distinguish the internal standard from the analyte during analysis, as the two will produce distinct signals in the mass spectrometer. In addition to its use as an internal standard in steroid analysis, 5β,19-Cycloandrostane-3,17-dione-d2 has also been studied for its potential as an anti-cancer agent. Research has shown that the compound can inhibit the growth of certain cancer cell lines, although further studies are needed to determine its full therapeutic potential. Overall, 5β,19-Cycloandrostane-3,17-dione-d2 is a valuable tool for researchers studying steroid hormones and their role in human health and disease.
