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.

(4-Chloro-pyrimidin-2-yl)-methyl-amine
CAS:Formula:C5H6ClN3Purity:97%Color and Shape:Liquid, No data available.Molecular weight:143.57Biuret (contains ca. 10% Triuret)
CAS:<p>Applications Biuret is used as a source of non-protein nitrogen in feed for ruminant. It is an impurity of urea based fertilizers as it has a poisonous effect on plants if present in high concentrations. Like peptide bonds, biuret forms violet-colored complexes with copper(II) ion in alkaline solution. This color change response is used to identify and quantify protein concentration (due to peptides present) and is known as biuret test.<br>References Li, J., et al.: Siliao Yanjiu, 1, 53 (2008); Kaasenbrood, P., et al.: J.
