4-({(Z)-[(4Z)-4-{[(4-hydroxyphenyl)amino]methylidene}cyclohexa-2,5-dien-1-ylidene]methyl}imino)cyclohexa-2,5-dien-1-one is a complex organic compound with a molecular formula of C18H15N2O2. It is characterized by a cyclohexa-2,5-dien-1-one core, which is a type of aromatic ketone. The compound features a Z-configured imino group attached to the cyclohexa-2,5-dien-1-ylidene system, which in turn is connected to a 4-hydroxyphenyl group through an aminomethylene bridge. This structure is indicative of a Schiff base, which is a common motif in various chemical and biological systems. The compound's complexity arises from the multiple conjugated double bonds and the presence of a phenolic hydroxyl group, which can participate in hydrogen bonding and other interactions. This specific arrangement of atoms and functional groups likely influences its chemical reactivity and potential applications in fields such as pharmaceuticals or materials science.

3731-86-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3731-86-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,3 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 3731-86:
(6*3)+(5*7)+(4*3)+(3*1)+(2*8)+(1*6)=90
90 % 10 = 0
So 3731-86-0 is a valid CAS Registry Number.

Structure-property relationship of highly ??-conjugated schiff-base moiety in liquid crystal diepoxide polymerization and mesophases stabilization

Liu, Huan,Fu, Zien,Xu, Kai,Cai, Hualun,Liu, Xin,Chen, Mingcai

, p. 7568 - 7577 (2011)

A study of the structure-property relationship of the highly ??-conjugated Schiff-base moiety in polymerization of a liquid crystal (LC) diepoxide oligomer (PBMBA) and mesophases stabilization has been investigated. We first proposed two exothermic peaks

PROBLEM TO BE SOLVED: To provide an aromatic diamine that gives a heat-cured product useful as an electric insulation material for radiating the heat generated from a semiconductor element and the like, and a liquid crystalline epoxy resin heat-cured product prepared therewith.SOLUTION: This invention relates to an aromatic diamine represented by formula (1), and a heat-cured product of the diamine and a liquid crystalline bisepoxide represented by formula (2) (where R-Rindependently represent a hydrogen atom, a C1-C6 alkyl group or a C1-C6 alkoxy group, m is an integer of 2-14, and Xis a divalent aromatic group).SELECTED DRAWING: None

Synthesis and characterization of new aromatic polyesters derived from new aromatic di- and tri hydroxyl monomers with 4-phenylenediacrylic acid and malonic acid

Mutar, Mohammed A.

, p. 7846 - 7852 (2015/02/02)

In the present work, six new aromatic polyesters (PE1-PE6) have been synthesized in high yields from the polycondensation between di- and tri hydroxyl monomers containing methylene unit, Schiff-base linkages and pyridine heterocyclic ring with 4-phenylenediacrylic acid and malonic acid using dibutyltin dilaurate as catalyst. The structure analysis of the polymers has been carried out by using FT-IR and 1H NMR spectroscopy. The monomers were characterized by FTIR and 1H NMR. FT-IR technique confirmed the esterification of di and tri hydroxyl monomers by the acid in all the polymers.
