Product Description

Pharmaceutical Materials Pyrimidine Powder Price For Sale

Pyrimidine, also known as m-diazobenzene, is a six-membered aromatic heterocyclic compound containing two m-nitrogen atoms, which is isomers with pyridazine and pyrazine. Molecular formula C4H4N2. Molecular weight 80.09. A colorless liquid or solid crystal with a pungent odor. The melting point is 20~22 degrees. The boiling point is 123~124 degrees Celsius. The refractive index is 1.4998 (20 C). It is easy to form salts with water, ethanol, ether, weak alkalinity and acid. Its alkalinity is weaker than pyridine, and its electrophilic substitution reaction is more difficult than pyridine. Bromination reaction can occur only in the 5-position. Nitrification and sulfonation can not occur, but nucleophilic substitution is more likely to occur. Pyrimidine derivatives are widely found in nature. For example, vitamin B1, uracil, cytosine and thymine contain pyrimidine structure. Picric acid is a yellow needle like crystal. The melting point is 156 degrees. Because of the existence of conjugated double bonds in pyrimidine, UV absorbency is strong. Barbituric acid is oxidized by three phosphorus oxychloride and then reduced by hydroiodic acid.
