Abstract Three pyrimidine derivatives, 6-amino-2-(benzylthio)-4(3H)-pyrimidinone (BTP-1), 6-amino-3-benzyl-2-(benzylthio)-4(3H)-pyrimidinone (BTP-2) and 6-(benzyloxy)-2-(benzylthio)-4-pyrimidinamine (BTP-3), were synthesized as corrosion inhibitors for mild steel in 3 M HCl solution. The inhibition performance of these three pyrimidine derivatives was studied by weight loss and electrochemical measurements, surface characterization, and theoretical calculations. It is found that these three pyrimidine derivatives act as mixed-type inhibitors with predominant cathodic effectiveness, and exhibit good inhibition performance with the order of BTP-1
