77582-61-7 Usage
General Description
Heneicosanoyl chloride is a type of fatty acid derived compound that is commonly used in organic synthesis. It belongs to the family of long-chain fatty acyl chlorides and is specifically derived from heneicosanoic acid, a 21-carbon fatty acid. Heneicosanoyl chloride is used as a reagent in various chemical reactions to introduce the heneicosanoyl group into organic molecules, such as in the formation of esters and amides. It is a colorless to pale yellow liquid with a strong, pungent odor and is known to be corrosive and highly reactive. Overall, heneicosanoyl chloride plays a significant role in organic chemistry as a versatile compound for creating complex molecules.
Check Digit Verification of cas no
The CAS Registry Mumber 77582-61-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,8 and 2 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77582-61:
(7*7)+(6*7)+(5*5)+(4*8)+(3*2)+(2*6)+(1*1)=167
167 % 10 = 7
So 77582-61-7 is a valid CAS Registry Number.

Mesogenic 3,6-bis(4-hydroxyphenyl)-1,2,4,5-tetrazine alkanoate esters
Fouad, Farid,Khabouchi, Faycal,Nielsen, Alek,Twieg, Robert
, p. 82 - 90 (2019/02/24)
A novel series of 3,6-bis(4-hdroxyphenyl)-1,2,4,5-tetrazine alkanoate esters were synthesized and their mesogenic properties were studied using differential scanning calorimetry (DSC) and polarizing optical microscopy (POM). The impact of changing the tail-core linkage from alkyl or alkoxy to ester is profound. Compared to the alkyl or alkoxy linkages, the ester linkage reduced mesogenic properties. Short-tailed compounds are non mesogenic (4a-4e), while long-tailed compounds (4f-4r) exhibit nematic phases. Unlike the alkyl or alkoxy tail series, none of the 18 presented esters in this series exhibits a smectic phase.
