C5H7N3

C5H7N3 is the molecular formula for several chemical compounds, meaning they all share the same number of atoms of carbon, hydrogen, and nitrogen. The precise arrangement of these atoms determines the specific compound and its properties. One common compound with this formula is 2-aminopyrimidine, a heterocyclic aromatic organic compound. 2-aminopyrimidine is a derivative of pyrimidine, a six-membered ring containing two nitrogen atoms. It plays a role in biological systems, as the pyrimidine ring is a fundamental component of nucleic acids.

Another possibility for C5H7N3 is 4-aminopyrimidine. Like 2-aminopyrimidine, it is an aromatic heterocyclic amine with a pyrimidine core. The difference lies in the position of the amino group attached to the ring. While less common in biological contexts than its isomer, it still possesses characteristic chemical reactivity due to the nitrogen atoms and the amino substituent. Other less common isomers might exist, each with distinct structural arrangements of the carbon, hydrogen, and nitrogen atoms, leading to different physical and chemical behaviors. The specific isomer is crucial for understanding its applications and properties, which can range from pharmaceutical intermediates to research chemicals.
