3-(4-Ethoxy-phenyl)-1H-quinazoline-2,4-dione is a complex organic compound with the molecular formula C16H13N2O3. It is a derivative of quinazoline, a heterocyclic compound with a fused benzene and pyrazine ring system. This specific compound features an ethoxy group (-OCH2CH3) attached to the para position of the phenyl ring, which is connected to the quinazoline core. The 2,4-dione part of the name indicates the presence of two carbonyl groups (C=O) at the 2nd and 4th positions of the quinazoline ring. 3-(4-ethoxy-phenyl)-1H-quinazoline-2,4-dione is of interest in medicinal chemistry due to its potential biological activities and may be used as a building block in the synthesis of various pharmaceuticals. It is typically synthesized through a series of chemical reactions and can be characterized by its physical and chemical properties, such as melting point, solubility, and spectroscopic data.

Check Digit Verification of cas no

The CAS Registry Mumber 2400-98-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,0 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2400-98:
(6*2)+(5*4)+(4*0)+(3*0)+(2*9)+(1*8)=58
58 % 10 = 8
So 2400-98-8 is a valid CAS Registry Number.

Metal and phosgene-free synthesis of 1H-quinazoline-2,4-diones by selenium-catalyzed carbonylation of o-nitrobenzamides

Wu, Xiaowei,Yu, Zhengkun

, p. 1500 - 1503 (2010)

1H-Quinazoline-2,4-diones were efficiently synthesized by selenium-catalyzed carbonylation of o-nitrobenzamides under relatively mild conditions. In situ-generated carbonyl selenide (SeCO) is proposed to initiate the catalytic carbonylation. Thus, a concise transition metal and phosgene-free synthetic route to potentially bioactive-substituted 1H-quinazoline-2,4-dione derivatives has been developed.
