3-Methoxyestra-1,3,5(10)-triene-4,17β-diol is a naturally occurring phytoestrogen, which belongs to the group of plant-derived compounds that have estrogen-like activity. This specific compound is a derivative of the estrane steroid nucleus, featuring a 3-methoxy group attached to the A-ring and a double bond at the 1,3,5(10) positions. The 4,17β-diol functional groups indicate the presence of two hydroxyl groups at these positions, which are crucial for its biological activity. It is found in certain plants and has been studied for its potential health benefits, particularly in relation to hormone regulation and the alleviation of menopausal symptoms. However, it is important to note that the safety and efficacy of 3-Methoxyestra-1,3,5(10)-triene-4,17β-diol in humans require further research and clinical trials.

5976-66-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5976-66-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,7 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5976-66:
(6*5)+(5*9)+(4*7)+(3*6)+(2*6)+(1*6)=139
139 % 10 = 9
So 5976-66-9 is a valid CAS Registry Number.

Methylation of catechol estrogen with diazomethane

Teranishi,Fujii,Yamazaki,Miyabo

, p. 3309 - 3314 (2007/10/02)

Dynamic aspects of methylation of catechol estrogen with diazomethane were investigated by means of thin-layer chromatography. The methylation rate of the hydroxyl group at the C-3 position was almost the same as that of the C-2 hydroxyl group in the reaction of 2-hydroxyestrogen, and 2-3 times that of the C-4 hydroxyl group in the reaction of 4-hydroxyestrogen. In these experiments, the maximum yields of 2-methoxyestrone, 2-hydroxyestrone 3-methyl ether, 4-methoxyesterone and 4-hydroxyesterone 3-methyl ether were 32, 39, 13, and 70%, respectively. In addition, demethylation of catechol estrogen dimethyl ethers with boron tribromide and synthesis of 4-hydroxyestrone monomethyl ethers are described.
