40089-91-6 Usage
General Description
4-Octylpyridine is a chemical compound with the formula C13H21N. It is a colorless to pale yellow liquid with a strong, unpleasant odor, and it is insoluble in water but soluble in organic solvents. 4-Octylpyridine is often used as a flavor and fragrance agent in the production of perfumes and other consumer products. It is also commonly used as an intermediate in the synthesis of pharmaceuticals, pesticides, and other fine chemicals. Additionally, 4-octylpyridine has been studied for its potential applications in organic light-emitting diodes and other optoelectronic devices due to its unique electronic and optical properties. However, it is important to handle this chemical with caution as it may be harmful if ingested, inhaled, or brought into contact with the skin.
Check Digit Verification of cas no
The CAS Registry Mumber 40089-91-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,0,8 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40089-91:
(7*4)+(6*0)+(5*0)+(4*8)+(3*9)+(2*9)+(1*1)=106
106 % 10 = 6
So 40089-91-6 is a valid CAS Registry Number.

Tetraphosphine/palladium catalysed Suzuki cross-coupling reactions of aryl halides with alkylboronic acids
Kondolff, Isabelle,Doucet, Henri,Santelli, Maurice
, p. 3813 - 3818 (2007/10/03)
Through the use of [PdCl(C3H5)]2/cis,cis, cis-1,2,3,4-tetrakis(diphenylphosphinomethyl)cyclopentane as a catalyst, a range of aryl bromides and chlorides undergoes Suzuki cross-coupling with alkylboronic acids in good yields. Several alkyl substituents such as ethyl, n-butyl, n-octyl, isobutyl or 2,2-dimethylpropyl on the alkylboronic acids have been successfully used. The functional group tolerance on the aryl halide is remarkable; substituents such as fluoro, methyl, methoxy, acetyl, formyl, benzoyl, nitro or nitrile are tolerated. Furthermore, this catalyst can be used at low loading, even for reactions of sterically hindered aryl bromides.
