This understanding is correct, however, the stabilizer content is approximately 70%. The lot-specific Certificate of Analysis will provide the exact stabilizer content, which can then be used to calculate the amount of β-Estradiol 3-Sulfate.

General description
β-Estradiol is secreted by developing ovaries and is predominant during premenopause in women.[1]
Application
β-Estradiol 3-sulfate sodium salt has been used to measure the estradiol level from culture supernatant in ultra-performance liquid chromatography-tandem mass spectrometry.[2]
Biochem/physiol Actions
β-Estradiol is a steroid hormone involved in a number of organ functions. It is significantly associated with brain functions including neuroprotection, neurogenesis and synaptic plasticity.[3] β-Estradiol maintains bone homeostasis, hence it is preferred for osteoporosis therapy.[4] 17-β-Estradiol is the most active estrogen generated in our body.[5] During postmenopausal, 17-β-estradiol inhibits oxidative modification in low density lipoprotein. This indicates that estrogen replacement therapy might be useful in treating cardiovascular disease.[6]

Female mammals have an enhanced baroreflex sensitivity compared with their male counterparts, leading researchers to speculate that estrogen modulates autonomic tone. Therefore, this study tests the hypothesis that exogenous estrogen can enhance the baroreflex sensitivity of male rats. Male Sprague-Dawley

We have characterized hepatic phenol sulfotransferase (SULT) activities in two benthic fish species, Mullus barbatus and Lepidorhombus boscii, using p-nitrophenol, dopamine, 17beta-estradiol, 4-nonylphenol, and 1-naphthol as substrates. High affinity sulfation of 17beta-estradiol was observed in both species (Km=28-75 nM), suggesting

The description of the product says that it contains 70 % N-methyl-D-glucamine as a stabilizer. Does this mean that 1.0 mg of the powder contains 0.3 mg of β-Estradiol 3-sulfate and that I need to weigh in 3.33 mg of the powder to get 1 mg of substance?
