Estrone 3-Valerate is used as a component in liquid crystal displays due to its cholesteric mesophase property. This property allows for the creation of unique display technologies with improved contrast, color, and viewing angles.
Used in Research and Development:
Estrone 3-Valerate is used as a research compound for studying the effects of Estrone and its derivatives on various biological processes. This helps in understanding the potential therapeutic applications and side effects of Estrone-based treatments.
Check Digit Verification of cas no
The CAS Registry Mumber 128788-26-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,8 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128788-26:
(8*1)+(7*2)+(6*8)+(5*7)+(4*8)+(3*8)+(2*2)+(1*6)=171
171 % 10 = 1
So 128788-26-1 is a valid CAS Registry Number.

Rhodium-Catalyzed Carbonylative Coupling of Alkyl Halides with Phenols under Low CO Pressure
Ai, Han-Jun,Li, Chong-Liang,Wang, Hai,Wu, Xiao-Feng
, p. 5147 - 5152 (2020/05/27)
A rhodium-catalyzed carbonylative transformation of alkyl halides under low pressure of CO has been developed. This robust catalyst system allows using phenols as the carbonylative coupling partner and, meanwhile, exhibits high functional group tolerance and good chemoselectivity. Substrates even with a large steric hindrance group or multiple reaction sites can be selectively converted into the desired products in good to excellent yields. A gram-scale experiment was performed and delivered an almost quantitative amount of the product. Control experiments were performed as well, and a possible reaction mechanism is proposed.
