17beta-Estradiol-2,4,16,16-d4 3-sulfate (sodium salt)

17beta-Estradiol-2,4,16,16-d4 3-sulfate is intended for use as an internal standard for the quantification of 17beta-estradiol-3-sulfate by GC- or LC-MS. 17beta-Estradiol-3-sulfate is a sulfated metabolite of the major premenopausal estrogen 17beta-estradiol (Cay-ISO60155, Cay-10006315). It is formed from 17beta-estradiol by estrogen sulfotransferase 1E1 (SULT1E1). 17beta-Estradiol-3-sulfate levels are increased in ovine fetal plasma.Formal Name: (17alpha)-3-(hydrogen sulfate) estra-1,3,5(10)-triene-2,4,16,16-d4-3,17-diol, monosodium salt.
