As a metabolite of Estradiol, it may have implications in the development of new drugs or therapies targeting hormone-related disorders.
Used in Research and Development:
In the field of research and development, 17-EPIESTRIOL serves as a valuable compound for studying the effects of Estradiol and its metabolites on the human body. It can be used in laboratory experiments to better understand the mechanisms of hormone action and develop new treatments for conditions influenced by hormonal changes.
Used in Quality Control and Impurity Profiling:
As an impurity in the production of Estradiol, 17-EPIESTRIOL is used in the quality control process to ensure the purity and safety of pharmaceutical products. It helps in the development of impurity profiles for Estradiol, which is crucial for maintaining the quality and efficacy of the final product.
Used in Hormone Replacement Therapy:
17-EPIESTRIOL, being a metabolite of Estradiol, may also be used in hormone replacement therapy (HRT) for conditions such as menopause, where the levels of Estradiol in the body decrease. It could potentially be utilized as a component in HRT formulations to help alleviate symptoms and maintain overall health.

Biochem/physiol Actions

17-epiestriol is an estradiol metabolite and a selective estrogen receptor (ER) beta agonist.

Check Digit Verification of cas no

The CAS Registry Mumber 1228-72-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,2 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1228-72:
(6*1)+(5*2)+(4*2)+(3*8)+(2*7)+(1*2)=64
64 % 10 = 4
So 1228-72-4 is a valid CAS Registry Number.

Cyclic Anti-Azacarboxylation of 2-Alkynylanilines with Carbon Dioxide

Miao, Bukeyan,Li, Suhua,Li, Gen,Ma, Shengming

, p. 2556 - 2559 (2016/07/06)

Direct anti-azacarboxylation of 2-alkynylanilines with CO2 mediated by ZnEt2 was observed to afford indole-3-carboxylic acids, a class of important compounds for the synthesis of many biologically active compounds, efficiently under 1 atm of CO2. The readily available nature of the different starting materials and tolerance of various functional groups provide vast opportunities for the efficient construction of diversified libraries for bioactive compounds listed in Figure 1. As an example, this methodology has been applied to the synthesis of Lotronex, a drug molecule used for the treatment of irritable bowel syndrome.
