Medchemexpress LLC 3-Amino-5-morpholinomethyl-2-oxazolidone | 43056-63-9 | 99.9% | 250 MG
AMOZ is a carcinogenic metabolite of Furaltadone that forms stable tissue residues by covalently binding to proteins as a hapten. It can be coupled with carrier proteins to induce an immune response and is released after acid hydrolysis. AMOZ residues can be detected by competitive ELISA and can be used as a typical marker to monitor drug residues in animal-derived foods for food safety.
