It is an organic acid and belongs to the class of benzoic acids. 2,5-DI(4-BUTYLOXYBENZYLOXY)BENZOIC ACID is characterized by the presence of two 4-butyloxybenzyloxy groups attached to the 2- and 5-positions of the benzoic acid core. It has a white crystalline appearance and is often used as a building block in organic synthesis and pharmaceutical research. The compound's unique structure and properties make it useful in the development of new drugs, materials, and chemical processes.

Check Digit Verification of cas no

The CAS Registry Mumber 205689-93-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,6,8 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 205689-93:
(8*2)+(7*0)+(6*5)+(5*6)+(4*8)+(3*9)+(2*9)+(1*3)=156
156 % 10 = 6
So 205689-93-6 is a valid CAS Registry Number.

Poly[(side-on mesogen)-Alt-(end-on mesogen)]: A compromised molecular arrangement

Wang, Meng,Bao, Wei-Wei,Chang, Wen-Ying,Chen, Xu-Man,Lin, Bao-Ping,Yang, Hong,Chen, Er-Qiang

, p. 5791 - 5800 (2019/08/26)

In recent years, sequence-controlled side-chain liquid crystal polymers (SCLCPs) have gained extensive interest because mesogenic units with different lengths and distributions can form various ordered sequences, which further endow LCP materials with diverse functions. In this manuscript, a side-chain side-on maleimide-containing monomer 2,5-bis-(4-butoxy-benzoyloxy)-benzoic acid 6-(2,5-dioxo-2,5-dihydro-pyrrol-1-yl)-hexyl ester (Y1801) and a side-chain end-on styrene-containing monomer 4′-[6-(4-vinyl-phenoxy)-hexyloxy]-biphenyl-4-carbonitrile (Y1802) are combined in one single macromolecular chain and orderly polymerized in an alternative sequence to form an alternating copolymer Poly(Y1801-Alt-Y1802). The chemical structure and alternating sequence of Poly(Y1801-Alt-Y1802) are confirmed by GPC and NMR techniques. The combination of DSC, POM, and WAXS data indicates that, although the side-on homopolymer PY1801 and the end-on homopolymer PY1802 both exhibit the nematic phase, their alternating copolymer Poly(Y1801-Alt-Y1802) shows an interdigitated smectic A phase, a compromised molecular arrangement instead. In addition, a strong fluorescence emission of Poly(Y1801-Alt-Y1802) is observed, which might provide this novel alternating-structured liquid crystal polymer with potential applications in luminescent materials and devices.

Polysiloxane-based liquid crystalline polymers and elastomers prepared by thiol-ene chemistry

Yang, Hong,Liu, Ming-Xia,Yao, Yue-Wei,Tao, Ping-Yang,Lin, Bao-Ping,Keller, Patrick,Zhang, Xue-Qin,Sun, Ying,Guo, Ling-Xiang

, p. 3406 - 3416 (2013/07/19)

A series of side-chain liquid crystalline polymers (LCPs) with polysiloxane backbones have been synthesized by grafting mesogenic monomers to poly[3-mercaptopropylmethylsiloxane] (PMMS) via thiol-ene click chemistry. Their properties were studied in detail by a combination of 1H NMR, gel permeation chromatography, thermogravimetric analysis, differential scanning calorimetry, polarized optical microscopy and small-angle X-ray scattering. In comparison with the traditional hydrosilylation method which requires noble metal catalyst platinum, this newly designed thiol-ene protocol produces polysiloxane-based LCPs with only anti-Markovnikov addition products under benign conditions. Moreover, by controlling the molar ratio of PMMS and mesogenic monomers, PMMS-based LCPs can be partially functionalized, meanwhile leaving spare mercapto groups, which could be further used as cross-linking sites to prepare polysiloxane-based liquid crystalline elastomers (LCEs). Besides preparing LCE fibers with a maximum contraction of 42% at nematic-to-isotropic transition temperature, we further explored the feasibility of using surface-rubbed cells to synthesize LCE films, but it turned out that this method could uniaxially align the mesogens of preformed short polymers but not the backbone chains so that the thermal-actuation effects of these films were modest.
