Properties and stability

Uridine is a related component of nucleic acid in animal cells and can increase the body’s antibody levels. Animal experiments show that the combination of uridine and inosine can promote myocardial cell metabolism, accelerate protein and nucleic acid biosynthesis and energy production, and can promote and improve brain cell metabolism.

Storage method

This product should be sealed and stored away from light.

Synthesis method

1. It can be prepared with 2,4-dichloro(trimethylsiloxy)pyrimidine.

Purpose

Uridine is a drug, such as anti-giant red blood cell anemia, treatment of liver, cerebrovascular, cardiovascular and other diseases. It is also a manufacturer of fluorouracil (S-FC), deoxynucleoside, iodoside (IDUR), bromoside (BUDR) ), fluoroside (FUDR) and other drugs are the main raw materials.
