4-Amino-1-[3,5-di-O-(4-chlorobenzoyl)-2-deoxy-α-D-ribofuranosyl]-1,3,5-triazin-2(1H)-one (4AAT) is an analytical chemical that is used for research and development purposes. 4AAT is a metabolite of the antibiotic ampicillin and has been identified as an impurity in the drug product. It can be synthesized from 2-(4'-chlorophenyl)benzaldehyde, 3,5'-di-O-(4'-chlorobenzoyl)-2',3'-dideoxyribose and sodium azide in a two step process with 98% purity. 4AATs are also found to be present in natural products such as honey or sugar cane juice.
