Product Name:Pyrimidine
English Name:Pyrimidine
CAS No.:289-95-2
Aliases:1,3-Diazine, m-Diazine
Molecular Formula:C4H4N2
Physical Properties:Colorless or slightly yellow low-melting crystalline solid or liquid with a pungent odor. Density 1.016 g/mL, melting point 20-22°C, boiling point 123-124°C, flash point 31°C. Soluble in water, ethanol, ether and other solvents. Weakly basic, forming crystalline salts with picric acid, oxalic acid, etc. Aromatic in character, yet sluggish in electrophilic substitution and oxidation reactions; nucleophilic substitution activity is also relatively low.
Uses:The pyrimidine ring is the core structural unit of nucleic acid bases such as cytosine, thymine and uracil, and serves as an important intermediate in the synthesis of numerous pharmaceuticals and agrochemicals. It is mainly used in the pharmaceutical industry for preparing sulfonamides, antiviral and antitumor drugs, and also as a fundamental raw material in fine chemical and organic synthesis.
