How is a solution prepared?
This is how solutions are prepared in the lab.
Step 1 of 8: Disinfect
The stoppers of both vials are wiped with an alcohol swab.
- Disinfect. The stoppers of both vials are wiped with an alcohol swab.
- Draw up. The needle passes through the stopper of the bacteriostatic water and the plunger draws up liquid.
- Transfer. The liquid runs down the inside wall of the vial with powder.
- Mix. The vial is gently swirled until the solution is clear.
- Done. The solution is ready for use in research.
- Take sample. A new needle passes through the stopper and the plunger draws up part of the solution.
- Sample vial. The solution runs through the septum of the screw cap into a sample vial.
- Analyze. The sample vial goes into the autosampler; the instrument measures the solution in vitro.

- Bridge
- A link between two positions in the chain.
The chain has 37 amino acids, shown here from the N-terminus to the C-terminus. The N-terminus carries a icosanedioyl-gGlu group, the C-terminus is an amide, and there is 1 bridge within the chain.

Origin and structure
Cagrilintide is derived from amylin, a peptide of 37 amino acids made in the beta cells of the pancreas. Kruse and colleagues at Novo Nordisk described its development in 2021 in the Journal of Medicinal Chemistry. A fatty acid is attached to the first amino acid through a short linker, and a disulfide bridge joins the cysteines at positions 2 and 7, as in amylin.
Compared with human amylin, the chain differs at six positions. Its CAS number is 1415456-99-3. As of November 2026, Cagrilintide is not authorized as a medicine. More in What is cagrilintide?
Purity and COA for every batch
Every batch of Cagrilintide goes to an external laboratory. There, HPLC measures purity (≥99%) and mass spectrometry confirms identity. The measured mass is compared with the calculated 4409 g/mol, which includes the linker and the fatty acid at the start of the chain. The COA for your batch number is on Lab results.
Storage and shipping
Keep the vial closed and store it cool, dry and dark, following the label and COA. We ship from Europe in insulated packaging with tracking, adding a cold pack in warm weather. Delivery takes 1–3 working days within Europe, within the EU only. Anything received and paid before 3 p.m. Central European time on a working day leaves the same day.
