Chemical Information
FooDB Name5,7-Dihydro-2-methylthieno[3,4-d]pyrimidine
Description5,7-Dihydro-2-methylthieno[3,4-d]pyrimidine belongs to the class of organic compounds known as thienopyrimidines. These are heterocyclic compounds containing a thiophene ring fused to a pyrimidine ring. Thiophene is 5-membered ring consisting of four carbon atoms and one sulfur atom. Pyrimidine is a 6-membered ring consisting of four carbon atoms and two nitrogen centers at the 1- and 3- ring positions. 5,7-Dihydro-2-methylthieno[3,4-d]pyrimidine is a chip, corn, and popcorn tasting compound. Based on a literature review very few articles have been published on 5,7-Dihydro-2-methylthieno[3,4-d]pyrimidine.
