Product Details

This peptide chain is the backbond of Semaglutide. Two amine residues (labeled with A and B) need to be conjugated with 

- a Boc-protected dipeptide CAS No. 2061897-68-3, consisting of a 2-methyl-alanine and a histidine

- two units of ethylene glycol (H2N-PEG2-CH2-COOH), a glutamic acid, and a C18 fatty acid Octadecadioic acid, which form another side chain CAS No. 1169630-40-3.

We offer two purity levels depending on your demand.

- 90% for the development of oral dosage form

- 98% for the development of injections


Due to the nature of peptide, we recommend the storage temperature at -15deg C to 20 deg C to avoid potential degradation.
