General Description

1H-Imidazole, 1-ethyl-2-methyl is a chemical compound with the molecular formula C6H8N2. It is a derivative of imidazole, a five-membered aromatic heterocycle with two nitrogen atoms. 1H-IMidazole, 1-ethyl-2-Methyl is known for its use in various chemical processes, including as a building block in the synthesis of pharmaceuticals and agrochemicals. It is a colorless to pale yellow liquid with a pleasant odor, and it is slightly soluble in water but more soluble in organic solvents. 1H-Imidazole, 1-ethyl-2-methyl is considered to be a valuable intermediate in organic synthesis due to its versatile reactivity and potential applications in the production of specialized compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 21202-52-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,0 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21202-52:
(7*2)+(6*1)+(5*2)+(4*0)+(3*2)+(2*5)+(1*2)=48
48 % 10 = 8
So 21202-52-8 is a valid CAS Registry Number.

The mechanisms of the formation of by-products in the catalytic synthesis of C-alkylimidazoles from diamines and carboxylic acids

Gitis, K. M.,Raevskaya, N. I.,Isagulyants, G. V.

, p. 895 - 898 (2007/10/02)

The formation of 1-ethyl-2-methylimidazole (1-Et-2-MI) and 1-ethyl-2-methylimidazoline (1-Et-2-MIN), intermediates in the synthesis of 2-methylimidazole (2-MI) from ethylenediamine (EDA) and AcOH in the presence of a platinum-on-alumina catalyst, was studied.Using CH3(14)COOH the incorporation of two acetate units into 1-Et-2-MI and 1-Et-2-MIN molecules was demonstrated.The same products were also obtained on dehydrogenation of 2-methylimidazoline (2-MIN) under mild conditions (220-230 deg C).A part of the latter is transformed to N-ethyl ethylendiamine (EEDA) and EDA.These facts indicate that both 1-Et-2-MI and 1-Et-2-MIN result from hydrogenolysis of the imidazoline ring with subsequent ethylation.A reverse reaction, the C5-cyclization of EEDA, was also observed.The formation of 2-MI is favored by increasing temperature.
