Storage Condition: Sealed, cool dry place (2-8℃), protected from light and air; avoid oxidizing agents; shelf life 2 years.

Main Uses

Pharmaceutical: Core API of proton pump inhibitors, used clinically for treating gastric ulcer, duodenal ulcer, reflux esophagitis, Zollinger-Ellison syndrome and anastomotic ulcer; inhibits gastric acid secretion by binding to (H?+K?)-ATPase, and has strong antibacterial effect on Helicobacter pylori.
Medical Research: Used as a research reagent to study the mechanism of gastric acid secretion, the treatment of digestive system diseases and the drug resistance of Helicobacter pylori.
Pharmaceutical Intermediate: Used in the synthesis of related derivatives and improved drugs (such as dexlansoprazole, the isomer of lansoprazole).
Quality Control: Used as a reference substance for drug quality detection and analytical chemistry experiments, ensuring the quality of related pharmaceutical products.
