Pteridine is an organic compound. It is made of a pyrazine ring and a pyrimidine ring that share one side. It has the same shape as naphthalene, but with four carbon atoms replaced by nitrogen atoms.

Replacing hydrogen in pteridine with something else gives a group of chemicals called pteridines. Pteridines do many different things in biology. Folate, also called vitamin B9, is an important pteridine for humans.[2]
