Purines and Pyrimidine Derivatives
Purines have a bicyclic structure, consisting of a six-membered ring fused to a five-membered ring, both containing nitrogen atoms in key positions. Purine derivatives, such as adenine and guanine, are essential for the formation of DNA and RNA. These compounds have therapeutic applications in cancer and viral disease treatments by inhibiting cell replication. Pyrimidines, on the other hand, have a monocyclic six-membered structure with two nitrogen atoms. Their derivatives, such as cytosine, thymine, and uracil, are also essential components of DNA and RNA and are used in chemotherapy and antiviral treatments.
At CymitQuimica, we offer purine and pyrimidine derivatives for research in molecular biology, genomics, and the development of innovative therapies.

CAS:3,4-Dihydro naratriptan is a medicinal compound that is used as an anti-migraine drug. It is a hydrogenated form of the parent molecule naratriptan and has been shown to have a reaction time of about 30 minutes when catalyzed by palladium. The impurity, 3,4-dihydro naratriptan sulfonamide, has been found to be less potent than the target compound and can be eliminated from the synthesis by using catalytic hydrogenation. 3,4-Dihydro naratriptan sulfonamide can also be reduced by catalytic hydrogenation to yield 3,4-dihydro naratriptan.Formula:C17H23N3O2SPurity:Min. 95%Molecular weight:333.45 g/mol4-amino-N-(4-methylpyrimidin-2-yl)benzenesulfonamide
