Controlled Product

CAS: 66789-03-5

17β-Estradiol-d4 is a steroid hormone that is used to prepare the standard curves for the analysis of estradiol in biological samples. The dry weight of 17β-Estradiol-d4 is determined by osmosis and water permeability. It can be analyzed using LC-MS/MS, which is a sensitive and specific method. This compound has been shown to have cancer preventive effects and to regulate women's reproductive cycle.
