4039-98-9 Usage
General Description
N,N-dimethyl-1,3,5-triazine-2,4-diamine, also known as melamine, is a chemical compound with the formula C3H6N6. It is a white crystalline solid that is commonly used in the production of plastics, adhesives, and flame retardants. Melamine is also a common component in the manufacturing of durable and heat-resistant dinnerware and kitchenware. Additionally, it is used as a nitrogen-rich fertilizer. However, melamine has been the subject of controversy due to its presence in some food products, especially in the 2008 Chinese milk scandal where melamine-contaminated infant formula caused widespread illness and death in China. In high doses, melamine has been found to be toxic to humans and animals, leading to kidney damage and failure. Therefore, it is important to handle and use melamine with caution and to ensure that it is properly regulated in consumer products.
Check Digit Verification of cas no
The CAS Registry Mumber 4039-98-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,3 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4039-98:
(6*4)+(5*0)+(4*3)+(3*9)+(2*9)+(1*8)=89
89 % 10 = 9
So 4039-98-9 is a valid CAS Registry Number.

Metal free [4+1] and [5+1] annulation reactions to prepare heterocycles using DMF and its derivatives as one-carbon source

, (2020/04/01)
1,2,4-Triazolo[3,4-a]pyridines and related heterocycles and substituted triazines were commonly discovered scaffolds in a variety of pharmaceutical and agrochemical agents. Herein, we report a highly efficient and practical method using DMF and its derivative for the [4+1] and [5+1] annulation reactions to prepare these heterocycles. This metal free reaction takes advantages of shelf stable DMF as solvent and carbon donor, imidazole chloride as a catalyst, the mild reaction condition tolerates a broad substrate range and substitutes. The prepared 3-unsubstituted 1,2,4-triazolo[3,4-a]pyridine and derivatives allow further introduction of a variety of functional group1 at 3-position.
