1,3-Cyclopentanedicarboxylic acid, 2,4-dioxo-, 1-(1,1-dimethylethyl) 3-ethyl ester

1-tert-Butyl 3-Ethyl-2,4-dioxocyclopentane-1,3-dicarboxylate is the proposed intermediate in the synthesis of Aflatoxin B2-d3(A357467) which is a labelled standard. Aflatoxins B1, B2, G1, G2 as secondary metabolites of fungal species such as Aspergillus flavus or Aspergillus parasiticus growing on a variety of foods (peanuts, nuts, spices, cereals). Aflatoxins are a group of very carcinogenic mycotoxins with hepatotoxic effects.Environmental contaminants; Food contaminants
