5342-78-9 Usage
General Description
2,2,4-Trimethyl-4-nitropentane, also known as isooctane, is a chemical compound with the molecular formula C8H18O2. It is a colorless liquid with a mild odor and is commonly used as a reference compound in octane ratings. Isooctane is a highly flammable and volatile compound and is often used as a component in gasoline to improve its combustion properties. It has a boiling point of 99.2 °C and is insoluble in water but soluble in most organic solvents. Isooctane is also used in the production of jet fuel, rubber, and as a solvent in various industrial applications. Its chemical properties and combustion characteristics have made it important in the development of more efficient and environmentally friendly fuels.
Check Digit Verification of cas no
The CAS Registry Mumber 5342-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,4 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5342-78:
(6*5)+(5*3)+(4*4)+(3*2)+(2*7)+(1*8)=89
89 % 10 = 9
So 5342-78-9 is a valid CAS Registry Number.

Kinetics and Mechanism of the C-Alkylation of Nitroalkane Anions by 1-Alkyl-2,4,6-triphenylpyridiniums: A Nonchain Reaction with Radicaloid Characteristics
Katritzky, Alan R.,Kashmiri, M. Akram,Ville, George Z. de,Patel, Ranjan C.
, p. 90 - 96 (2007/10/02)
The C-alkylation of 2-nitropropanide by N-substituted pyridiniums is first order in each reactant in Me2SO.The effect on the rate of temperature , N substituent, leaving group, and nucleophile was studied quantitatively.Overall, the evidence excludes an SN2 displacement and suggests that the reactions proceed by a free radical nonchain mechanism.
