Description
Diethylstilbestrol Dimethyl Ether, also known as DES-Dimethyl Ether, is a synthetic compound derived from the methylation of diethylstilbestrol (DES). It is characterized by its attractant activity towards zoospores, which are a type of motile spore found in certain fungi and algae.
Uses
Used in Agricultural Applications:
Diethylstilbestrol Dimethyl Ether is used as an attractant for zoospores in the agricultural industry. The attracted zoospores encyst and then germinate in the presence of DES-Dimethyl Ether, which can be utilized for various purposes such as pest control or studying the life cycle of these organisms.
Used in Research and Development:
In the field of research and development, Diethylstilbestrol Dimethyl Ether serves as a valuable tool for studying the behavior and biology of zoospores. By understanding how these spores respond to the compound, scientists can gain insights into their ecological roles and potential applications in various fields, such as agriculture, biotechnology, and environmental management.

Manufacturing Process
20 g of 1-(1-chlorobutyl)-4-methoxybenzene is dissolved in 50 ml of ether
which had been dried over sodium. Separately, 2.8 g of magnesium turnings
are covered with 20 ml of ether. 0.2 g of iodine, as a catalyst, is added and
the solution of 1-(1-chlorobutyl)-4-methoxybenzene is added at such a rate as
to keep the ether refluxing gently. If there action dopes not start immediately
after the addition of a few drops of the halide, the solution may be heated
cautiously in order to start the reaction. The mixture is then refluxed for
another 0.5 hour and then allowed to cool down. During the whole reaction a
current of hydrogen or nitrogen is passed through the apparatus. The
resulting grignard reagent is filtered, cooled to -10°C and added slowly to a
solution of 18 g of 1-(methoxyphenyl)-propan-1-one in 20 ml benzene to
which 0.2 g of MnCl2. The grignard reagent is added so slowly that the
temperature is kept below 0°C. After 2 hours, the temperature is raised to
room temperature and the solvent distilled off in vacuo. The residue is heated
to 170°C at a pressure of 0.4 mm Hg. MgCl(OH) is split off and the product
distils over. This compound is dealkylated by heating it for 20 hours with a
solution of KOH in glycerin at 190°C in an atmosphere of nitrogen to obtain
α,α-diethyl-4,4'-dimethoxystilbene.

Check Digit Verification of cas no
The CAS Registry Mumber 130-79-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130-79:
(5*1)+(4*3)+(3*0)+(2*7)+(1*9)=40
40 % 10 = 0
So 130-79-0 is a valid CAS Registry Number.

The reductive coupling of alkyl aryl ketones 1 - 3 and 7 - 9 by low valent titanium salts yields predominantly the (Z)-isomers of 11 - 13 and 17 - 19.Evidence is given by 1H NMR spectroscopy.This behavior can be explained by ?-complex formation of phenyl rings with Ti0.Severe steric hindrance, however, favors the (E)-isomers ( -> 14 and 15).Donor groups in p-position, particularly, give increasing amounts of pinacols, 23 - 27, which undergo rearrangement to the ketones 28 and 29.
