2398-68-7 Usage
General Description
Eicosylbenzene is a hydrocarbon compound that is commonly used as a standard for gas chromatography (GC) analysis. It belongs to the group of alkenes, which are organic compounds consisting of carbon and hydrogen atoms. Eicosylbenzene is a long-chain alkylbenzene, meaning it has a 20-carbon chain attached to a benzene ring. In GC analysis, eicosylbenzene is used as a reference substance to calibrate and evaluate the performance of the chromatographic system. Its use as a standard allows for the accurate identification and quantification of other relevant compounds in a given sample. Eicosylbenzene is also used as a reference material for the analysis of petroleum products and environmental samples.
Check Digit Verification of cas no
The CAS Registry Mumber 2398-68-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,9 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2398-68:
(6*2)+(5*3)+(4*9)+(3*8)+(2*6)+(1*8)=107
107 % 10 = 7
So 2398-68-7 is a valid CAS Registry Number.

Stille cross-coupling of activated alkyltin reagents under "ligandless" conditions
Herve, Agnes,Rodriguez, Alain L.,Fouquet, Eric
, p. 1953 - 1956 (2007/10/03)
(Chemical Equation Presented) Monoalkyltins activated by a fluoride source are shown to be as reactive as their vinyl or aryl homologues in the Stille coupling reaction, thus providing an easy entry into the pallado-catalyzed formation of Csp3-Csp2 bonds. In addition to this uncommon reactivity, this methodology holds several advantages such as (i) a quantitative preparation of stable and easy to handle alkyltin reagents 2, (ii) a simplified coupling procedure without any phosphine added ligand under neutral conditions, and (iii) a facile purification step of the organic products from the inorganic nontoxic tin byproducts.
