Application:
21,39-di-tert-butyl 1-(2,5-dioxopyrrolidin-1-yl) (S)-9,18,23-trioxo-2,5,11,14-tetraoxa-8,17,22-triazanonatriacontane-1,21,39-tricarboxylate is used as an intermediate for Semaglutide.
Packaging:
1g/bottle, 3g/bottle, 5g/bottle, 10g/bottle or according to the specific requirements from customers.
Recommended Storage Conditions:
Short-term storage at room temperature; more than three months is best stored at 2-8 degrees Celsius; more than one year is best stored at -20±5 degrees Celsius.
For reducing the absorption of the moisture, it should be slowly warmed to ambient temperature before opened.
Shelf Life:
24 months if stored under above conditions.
