Properties and stability
Together with xanthine, it is widely present in animals and plants. The inosinic acid of its nucleotide is the precursor of the purine nucleotide of nucleic acid. It is also the parent body of caffeine. Hypoxanthine can be produced through the action of adenine deaminase or nitrite.Purine deamination can also result in the phosphorolysis of inosine through nucleoside phosphorylase.
Storage method
This product should be kept sealed, cool and dry.
Synthesis method
Ethyl cyanoacetate, sodium ethoxide, and thiourea The combination reaction gives 2- Thiol-4-Amino -6-Hydroxypyrimidine , and then undergo nitrosation, reduction, elimination, and cyclization to obtain 6-Hydroxypurine.
Purpose
Anti-malignant tumor drugs6-Intermediate of mercaptopurine.
