CAS :3-(4-Methylbenzoyl)propionic acid (MBPA) is a corrosion inhibitor that can be used to protect metals and other materials from damage caused by acidic substances. MBPA has been shown to adsorb onto the surface of metal, forming a protective layer that prevents corrosion. This compound is synthesised by reacting methyl groups with aluminium chloride in an organic solvent to form the hydroxy group. The carboxylate group reacts with the hydroxyl group and forms the ligand, which is then reacted with phosphonic acid to produce MBPA. Molecular modelling studies have shown that this ligand binds to the metal surface through its hydrophobic interactions, which are stronger than its hydrogen bonds.Formule :C11H12O3Degré de pureté :Min. 95%Couleur et forme :Off-White PowderMasse moléculaire :192.21 g/mol1-Pyrazin-2-yl-[1,4]diazepane
