This product is offered based on the Estradiol content. The 100 mg package size will contain 100 mg of Estradiol, however the bulk of the mass in the bottle will be 2-hydroxypropyl-β-cyclodextrin. For example, a lot reporting a 48 mg/g estradiol content will have approximately 2.08 grams of powder material in the vial. Please see the link below to review additional information regarding water-soluble complexes and cyclodextrins:

General description
β-estradiol is a natural human estrogen. It is vital for the growth of breast and reproductive epithelia, maturation of long bones and development of secondary sexual characteristics. Estradiol is produced by immature germ cells, spermatozoa, Leydig cells and Sertoli cells. β-estradiol acts as a menopausal hormones. It is involved in replacement therapy for female hypogonadism or primary ovarian failure. Reduced levels of β-estradiol are linked to heart disease and osteoporosis. Estradiol plays a critical role in proliferation, modulation of ion transport and control of apoptosis in Sertoli cells. It maintains sperm concentration, motility and morphology.
Application
β-estradiol has been used:
- to culture differentiated adipocytes
- for estradiol treatment in rats
- for oocyte maturation in vitro
Packaging
Package size based on estradiol
Other Notes
Contains 40-55 mg estradiol per gram of solid; balance 2-hydroxypropyl-β-cyclodextrin.

what is the molecular weight of E-4389 product?
1 answer-
This is a dual-component product. A single molecular weight does not apply. The molecular weight of the B-estradiol is 272.38 grams per mol, and the molecular weight of the 2-hydroxypropyl-β-cyclodextrin is 1396 grams per mol. The package size of 100 mg is in reference to the B-Estradiol. This product contains 40 - 50 mg per gram solid. The lot-specific B-estradiol content is reported in the Certificate of Analysis.

How do I calculate the molarity of product E4389, β-Estradiol - Water Soluble?
1 answer-
Product E4389 (β-Estradiol-Water Soluble) is a complex of β-Estradiol and cyclodextrin. Cyclodextrin is used to aid in the solubility of β-Estradiol into water. In order to prepare a molar solution of β-Estradiol you will have to base it on the β-Estradiol content in the solution and not the entire complex.
