Provided herein is a method to mimic and assess the chemical degradation risk of a biological product, in prefilled syringes (PFS), using a custom-designed mimetic peptide. Such method is also able to predict the susceptibility to degradation of biological product in solution in a container for medical usage. 2. The method according to further comprising after step iv) claim 1 , a measurement step v) by mass spectrometry and a step vi) of identification of the chemical degradation.3. The method according to wherein R claim 1 , R claim 1 , Rand Reach represent CH claim 1 , and X═H claim 1 , n=1 and m=1.4. The method according to wherein the aqueous solution prepared at step i) comprises from 30 to 100% of water claim 1 , mass percentage.5. The method according to wherein the aqueous solution prepared at step i) further contains excipients claim 1 , buffering agents claim 1 , acids claim 1 , bases claim 1 , salts claim 1 , preservatives claim 1 , solubilizers claim 1 , surfactants claim 1 , chelating agents claim 1 , sugars claim 1 , amino acids claim 1 , peptides claim 1 , solvents and combinations thereof.6. The method according to wherein the aqueous solution prepared at step i) comprises at least 5 μg/ml of the compound of formula (I).7. The method according to wherein the part of the container for medical usage is a syringe claim 1 , a prefillable syringe claim 1 , part of a prefillable syringe claim 1 , a prefilled syringe or part of a prefilled syringe.8. The method according to wherein the part of the container for medical usage is a barrel claim 1 , a tip cap claim 1 , a cap claim 1 , a needle or a plunger stopper.9. The method according to wherein the part of the container for medical usage is glass claim 1 , rubber claim 1 , adhesive claim 1 , silicon oil claim 1 , plastic claim 1 , or metal.10. The method according to wherein the duration of step ii) is in a range from 4 hours to 2 months.11. The method according to wherein step ii) is carried out at a ...
