26902-76-1 Usage
General Description
4'-Ethoxyl-2,2,2-trifluoroacetophenone is a chemical compound that belongs to the class of organic compounds known as trifluoromethylbenzenes. These are aromatic compounds that contain a benzene substituted by one or more trifluoromethyl groups. The characteristic trifluoroacetophenone component imparts unique physical and chemical properties, including high thermal and chemical stability and a strong polar nature due to the presence of fluorine atoms. This chemical is not commonly found in nature and is typically utilized in various industrial and laboratory syntheses, potentially as a precursor to other compounds or as a reagent with specific chemical activity. The specific properties and uses of 4'-Ethoxyl-2,2,2-trifluoroacetophenone can vary based on the context of its application.
Check Digit Verification of cas no
The CAS Registry Mumber 26902-76-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,0 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 26902-76:
(7*2)+(6*6)+(5*9)+(4*0)+(3*2)+(2*7)+(1*6)=121
121 % 10 = 1
So 26902-76-1 is a valid CAS Registry Number.

The reduction of aryl trifluoromethyl ketones by sodium borohydride. The hydride transfer process
Stewart, Ross,Teo, K. C.
, p. 2491 - 2496 (2007/10/02)
The rates of reduction of 17 aryl trifluoromethyl ketones by sodium borohydride in 2-propanol have been measured.The rho (ρ) value is 3.12, excluding the 4-amino and 4-dimethylamino groups, which both lower the rate to a greater extent than their ? values predict.The close correspondence between substituent effects for hydride addition in the methyl and trifluoromethyl series (excluding the amino groups) suggests that normal substituent effects are to be expected for oxidation processes involving hydride removal in trifluoromethyl compounds.The present results are consistent with the oxidation of aryl trifluoromethyl carbi ols by permanganate taking place by hydrogen atom abstraction.The effect of substituents on the rate of reduction of the trifluoromethyl ketones is almost identical to that on the equilibrium constant for formation of the ketone hydrates.The application of the reactivity-selectivity principle to the reduction reaction is also considered.Reduction of the 4-ethyl compound has ΔH = 2.7 kcal mol-1 and ΔS = -38 cal deg-1 mol-1.
