81-29-8 Usage

Uses

1,3,6,8-Tetrachloropyrene does not have any known beneficial applications due to its highly toxic and mutagenic nature. Efforts should be focused on controlling and reducing its release into the environment to minimize its impact on public health and ecosystems.

Check Digit Verification of cas no

The CAS Registry Mumber 81-29-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81-29:
(4*8)+(3*1)+(2*2)+(1*9)=48
48 % 10 = 8
So 81-29-8 is a valid CAS Registry Number.

Synthesis and phase structures of novel π-acceptor discotic liquid crystalline compounds having a pyrenedione core

Yasutake, Mikio,Fujihara, Takashi,Nagasawa, Akira,Moriya, Keiichi,Hirose, Takuji

, p. 4120 - 4125 (2008)

Several π-acceptor discotic liquid crystalline compounds were synthesized by using a pyrenedione unit as a core. Terrace-like and band-like structures were revealed by polarized optical microscopy (POM) observations and XRD measurements. In conjunction with the results of the single-crystal structure analysis of analogous crystalline compounds, all of the liquid crystalline compounds were confirmed to form a discotic lamellar phase D L2.

Induction and control of columnar mesophase by charge transfer interaction and side chain structures of tetrasubstituted pyrenes

Hirose, Takuji,Kawakami, Osamu,Yasutake, Mikio

, p. 65 - 74 (2006)

The induction of the columnar phase is described in which intrinsically crystalline 1,4,6,9-tetraacyloxypyrenes have been mixed with tetranitrofluorenone, TeNF, as an electron acceptor. The pyrene derivative with linear nonyl chains, PC 9, has not shown any mesophases using trinitrofluorenone, suggesting that stronger charge transfer interaction is favored by TeNF. The shape of the substituents works to control the mesophase type: the mixture of PC 9 and TeNF has formed a rectangular columnar phase, and a hexagonal columnar phase is attained by rounder derivatives bearing branched side chains.
