Abstract Amino acids are the promising biomolecules as eco-friendly inhibitors for the corrosion protection of materials. In this work, two amino acid derivatives (MPT and BPT) were synthesized as green inhibitors, and their corrosion inhibition performance for N80 carbon steel in CO2-saturated formation water was studied by electrochemical tests and surface analysis. It is found that both MPT and BPT exhibit outstanding inhibitive effect (inhibition efficiency of 99.26 % for MPT and 99.44 % for BPT), which is significantly higher than those already reported amino acid derivative inhibitors. The inhibition mechanism of MPT and BPT was also revealed by theoretical calculations.
