13067-81-7 Usage
General Description
2-Ethylhexyllithium is a highly reactive organometallic compound that is used as a strong base in organic synthesis. It is a lithiated alkyl compound and a powerful nucleophile, and is commonly employed in the formation of carbon-carbon bonds and in the synthesis of complex organic molecules. Due to its high reactivity, it must be handled with extreme caution, as it is sensitive to air, moisture, and other impurities. Additionally, it must be stored and handled under an inert atmosphere to prevent spontaneous reactions. It is also highly flammable and can react violently with water, acids, and other common organic compounds, making it a dangerous and challenging chemical to work with.
Check Digit Verification of cas no
The CAS Registry Mumber 13067-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,6 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13067-81:
(7*1)+(6*3)+(5*0)+(4*6)+(3*7)+(2*8)+(1*1)=87
87 % 10 = 7
So 13067-81-7 is a valid CAS Registry Number.

NMR spectra of a hydrocarbon-soluble organosodium compound and its lithium analogs

, p. 838 - 840 (1996)
1H, 23Na, and 7Li NMR spectra of 2-ethylhexylsodium, 2-ethylhexyllithium, and isobutyllithium obtained in the reaction of the corresponding alkyl chlorides and metals have been recorded. The 1H NMR signal for the protons of the CH2Na group is shifted upfield compared with that for the protons of the CH2Li group (doublets at δ -0.88 and δ -0.83, respectively). The composition of the products of reaction of 2-ethylhexyl chloride with sodium depends on the form of the metal reagent employed. The use of sodium balls with diameter up to 2 mm results in the formation of products containing ionic chlorine (30-50 % with respect to Na); the reaction with the dispersion proceeds faster and the reaction product is chlorine-free. The 23Na NMR spectra of these substances are also different, which is explained by the formation of 2-ethylhexylsodium complexes with NaCl in the former case.
