Pyrimidine CAS 289-95-2

Pyrimidine is a colorless crystal or liquid with a characteristic bitter almond odor. As the core structure of nucleic acid bases (e.g. cytosine, uracil), its high reactivity and heterocyclic stability stand out, it needs to be sealed and kept away from light, avoiding contact with strong oxidizing agents.
