CAS 1089-80-1: 9-Dehydroestrone
Description:9-Dehydroestrone is a steroid hormone and a derivative of estrone, classified under the category of estrogens. It is characterized by its unique molecular structure, which includes a phenolic A-ring and a ketone group at the C-17 position. This compound is primarily recognized for its role in the biosynthesis of estrogens and its potential biological activities, including effects on reproductive tissues and bone metabolism. 9-Dehydroestrone is typically found in trace amounts in human plasma and is of interest in both clinical and research settings, particularly in studies related to hormone replacement therapy and endocrine disorders. Its chemical properties include moderate solubility in organic solvents and limited solubility in water, which influences its bioavailability and pharmacokinetics. As with many steroid hormones, it can undergo various metabolic transformations in the body, leading to the formation of other biologically active compounds. Safety and handling precautions are essential when working with this substance, as it may have hormonal effects and potential toxicity at certain concentrations.
