4(3H)-Quinazolinone, 3-amino-2-[2-(2,4-dimethoxyphenyl)ethyl]- is a complex organic compound with the molecular formula C18H22N2O4. It is a derivative of quinazolinone, a heterocyclic compound with a quinazoline ring system. This specific compound features an amino group at the 3-position, an ethyl group at the 2-position, and a 2,4-dimethoxyphenyl group attached to the ethyl group. The presence of the dimethoxyphenyl group provides additional functional groups, specifically two methoxy groups, which can influence the compound's reactivity and properties. This chemical is primarily used in the synthesis of various pharmaceuticals and biologically active molecules due to its unique structure and potential to form stable interactions with target proteins.

Check Digit Verification of cas no

The CAS Registry Mumber 92617-46-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,6,1 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 92617-46:
(7*9)+(6*2)+(5*6)+(4*1)+(3*7)+(2*4)+(1*6)=144
144 % 10 = 4
So 92617-46-4 is a valid CAS Registry Number.

Intramolecular Reactions of N-Nitrenes: Oxidation of 3-Amino-2-(2,4-dimethoxyphenylethyl)quinazolin-4(3H)-ones

Atkinson, Robert S.,Gawad, Nagwa A.

, p. 335 - 340 (2007/10/02)

Oxidation of the N-aminoquinazolones (5) and (6) gave the 1H-azepines (7) and (10) respectively.Boat-to-boat flipping of the azepine ring in compound (7) is slow on the n.m.r. time-scale even at 140 deg C.Heating of compound (10a) in chlorobenzene at 135 deg C brings about interconversion with the stereoisomer (10b) with a minimum free energy barrier of 30 kcal mol -1.Possible reasons for this high barrier to azepine ring inversion are examined.
