2553-34-6 Usage
Chemical structure
17-ethylestradiol is a synthetic estrogen hormone with a chemical structure similar to the natural hormone estradiol.
Usage
It is commonly used as a component in oral contraceptives and hormone replacement therapy.
Mechanism of action
17-ethylestradiol works by binding to estrogen receptors in the body, leading to changes in the reproductive system and other organs.
Potency
It has been found to have a higher potency than natural estradiol, making it effective at very small doses.
Side effects
It has the potential to cause side effects such as nausea, breast tenderness, and changes in menstrual bleeding.
Environmental impact
17-ethylestradiol may pose environmental and health risks due to its presence in water systems and potential endocrine-disrupting effects on aquatic organisms.
Check Digit Verification of cas no
The CAS Registry Mumber 2553-34-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,5 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2553-34:
(6*2)+(5*5)+(4*5)+(3*3)+(2*3)+(1*4)=76
76 % 10 = 6
So 2553-34-6 is a valid CAS Registry Number.

The hydrogenation catalyzed heterogeneously by palladium on boron nitride (Pd/BN) in methanol realized the chemoselective hydrogenation of only azides, alkenes, and alkynes in the presence of other reducible functionalities such as benzyl ethers, aryl halides, aryl ketones, and nitro groups. Furthermore, the totally chemoselective semihydrogenation of alkynes could also be achieved without the reduction of other coexisting reducible functionalities, which include azides and alkenes, by using Pd/BN in pyridine as a solvent. Be unique, be selective: The chemoselective hydrogenation of azides, alkenes, and alkynes was achieved without the reduction of other reducible functionalities by the use of a heterogeneous palladium on boron nitride (Pd/BN) catalyst. Furthermore, Pd/BN was applicable to the unique and chemoselective semihydrogenation of alkynes without the reduction of azido functionalities in the presence of pyridine or diethylenetriamine.
