29743-08-6 Usage
General Description
Ethyl benzoate (EB) is an ester formed by the condensation of benzoic acid and ethanol. This colorless liquid has the odor of flowers, and is used as a flavoring agent in foods and as a fragrance in soaps and perfumes. It occurs naturally in tuberose, hyacinth, and ylang-ylang. Ethyl benzoate is also used as a solvent for various chemical reactions and as a plasticizer. It is also used in the synthesis of dyes, pharmaceuticals, and pesticides. It has low toxicity and is not known to cause any harmful effects to the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 29743-08-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,7,4 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 29743-08:
(7*2)+(6*9)+(5*7)+(4*4)+(3*3)+(2*0)+(1*8)=136
136 % 10 = 6
So 29743-08-6 is a valid CAS Registry Number.

Organic thermotropic nematic compounds
-
, (2008/06/13)
A new family of organic thermotropic nematic compounds comprising N-(para-substituted alkoxy-benzylidene)-anilines having also a para-n-butyl substituent on the aniline ring. These compounds have the following structural formula: STR1 wherein R is a straight chain alkyl group containing 1 to 4 carbon atoms and R' is n-butyl. Synthesis involves combining the desired p-substituted benzaldehyde and p-n-butyl aniline in equimolar proportions in anhydrous ethyl alcohol with glacial acetic acid as catalyst. The resulting homologous series of compounds are useful as materials which undergo a change in optical properties under the influence of externally applied energy, preferred members of which, either individually or in binary mixtures, have melting points near room temperature, a broad nematic mesomorphic temperature range within an overall range of about 0° to about 70° C., low viscosity in the nematic phase, good stability, and substantially no color.
