121554-14-1 Usage

General Description

2-(octyloxy)benzonitrile, also known as 2-n-octoxybenzonitrile, is a chemical compound with the molecular formula C16H23N. It is a nitrile derivative with a benzene ring and a long aliphatic chain. 2-(OCTYLOXY)BENZONITRILE is commonly used as a liquid crystal material, particularly in the production of liquid crystal displays (LCDs). Its properties make it suitable for modifying the physical and optical properties of liquid crystal materials, such as increasing their clearing point temperatures and enhancing their stability. Additionally, 2-(octyloxy)benzonitrile is also used in the synthesis of other organic compounds and may have potential applications in pharmaceuticals and other industries.

Check Digit Verification of cas no

The CAS Registry Mumber 121554-14-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,5,5 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121554-14:
(8*1)+(7*2)+(6*1)+(5*5)+(4*5)+(3*4)+(2*1)+(1*4)=91
91 % 10 = 1
So 121554-14-1 is a valid CAS Registry Number.

Two ways of preparing benzonitriles using BrCCl3-PPh3 as the reagent

Jasem, Yosef Al,Barkhad, Mohamed,Khazali, Mona Al,Butt, Hifsa Pervez,El-Khwass, Noha Ashraf,Azani, Mariam Al,Hindawi, Bassam Al,Thiemann, Thies

, p. 80 - 84 (2014/03/21)

Benzamides were converted into benzonitriles with BrCCl3- PPh3-Et3N in CH2Cl2 in an Appel-type reaction. Benzaldoximes could be transformed to benzonitriles under identical conditions. It was found that the reaction system BrCCl3-(2 equiv.)PPh3 was also suitable for these transformations with PPh 3 replacing Et3N.

The Synthesis and Transition Temperatures of Some Lateral Cyano-Substituted-1,1':4',1''-terphenyls

Hird, Michael,Gray, George W.,Toyne, Kenneth J.

, p. 205 - 221 (2007/10/02)

In recent years we have used palladium-catalysed cross-coupling procedures to prepare a large number of very interesting lateral mono- and di-fluoro-substituted terphenyls.Similar methodology has been applied in the synthesis of lateral cyano-substituted terphenyls to assess the extent to which the mesophases of such systems can tolerate the larger cyano group; the synthetic routes to these compounds are discussed in detail.The compounds with the lateral cyano-substituent in the centre ring have very low melting points and liquid crystal phases exhibited (SC, SA and nematic) are dependent on the terminal substituents.The compounds with the cyano-substituent at the edge of the terphenyl core are still quite low melting and they have very wide SA ranges. Keywords: lateral cyano-substitution, 1,1':4',1''-terphenyls, palladium-catalysed cross-coupling
