3,6-Dimethyl-3,4-dihydro-5H-1,2,3-triazolo[4,5-d]pyrimidine-5,7(6H)-dione is a complex organic compound with the molecular formula C7H8N4O2. It is a derivative of the triazolopyrimidine class of molecules, characterized by the presence of a triazole ring fused to a pyrimidine ring. 3,6-Dimethyl-3,4-dihydro-5H-1,2,3-triazolo[4,5-d]pyrimidine-5,7(6H)-dione features two methyl groups at the 3rd and 6th positions, and it exists in a dihydro form, indicating the presence of two hydrogen atoms in a reduced state. The compound has two carbonyl groups, one at the 5th position and another at the 7th position, which contribute to its dione classification. It is a white crystalline solid and is known for its potential applications in medicinal chemistry, particularly as a building block for the synthesis of biologically active molecules. The compound's structure and properties make it a subject of interest in the field of heterocyclic chemistry, where it may be explored for its potential therapeutic effects or as a chemical intermediate in the pharmaceutical industry.

Check Digit Verification of cas no

The CAS Registry Mumber 2278-14-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,7 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 2278-14:
(6*2)+(5*2)+(4*7)+(3*8)+(2*1)+(1*4)=80
80 % 10 = 0
So 2278-14-0 is a valid CAS Registry Number.

Synthesis and regioselective N- and O-alkylation of 1H- or 3H-[1,2,3]triazolo[4,5-d]pyrimidine-5,7(4H,6H)-diones (8-azaxanthines) and transformation of their 3-alkyl derivatives into 1-alkyl isomers

Islam, Rafiqul,Nagamatsu, Tomohisa

, p. 4167 - 4179 (2008/03/13)

Several alkylating agents, for example alkyl halides and dimethyl sulfate, were employed in aprotic solvents under a variety of conditions for the alkylation of mono- and disubstituted 1H- or 3H-[1,2,3]triazolo[4,5-d] pyrimidine-5,7(4H,6H)-diones, which were prepared by cyclization of the appropriate 5,6-diaminouracils with nitrous acid. The alkylation on the triazole ring in the presence of anhydrous potassium carbonate took place simultaneously at the 1- and 2-positions, with alkylation at the 2-position taking priority. Similar alkylation on the pyrimidine ring with an equivalent alkylating reagent took place only at the 4-position. The alkylation of 3,6-disubstituted derivatives at room temperature led to 5-O-alkylation accompanied by 4-N-alkylation, but at high temperature only 4-N-alkylation took place. Reaction of 3,4,6-trisubstituted derivatives with excess alkylating agent at high temperature leads to the formation of 1,4,6-trisubstituted derivatives with elimination of the 3-substituent.

The quaternization of methyl derivatives of 8-azaxanthine by various alkylating agents was studied.These compounds form two series of quaternary salts, i.e., 7,8- and 7,9-dimethyl-8-azaxanthinium.When heated, all the quaternary salts undergo rearrangement
