Zearalenone-13C18 (Synonyms: FES-13C18, Mycotoxin F2-13C18, Toxin F2-13C18, Zenone-13C18)

Zearalenone-¹³C₁₈ is intended for use as an internal standard for the quantification of zearalenone by GC- or LC-MS. Zearalenone is a mycotoxin that has been found in Fusarium and has estrogenic activities.¹ It binds to human estrogen receptor α (ERα) and ERβ (IC₅₀s = 9 and 5.8 nM, respectively).² Zearalenone induces precocious development of mammary tissues in young female pigs and prepucial enlargement in young male pigs.³ Zearalenone (1.5-5 mg/kg of diet) induces hyperestrogenism in pigs. It also induces degeneration of meiotic chromatin in oocytes and reduces fertility in pigs when administered at a dose of 200 µg/kg.⁴ Zearalenone has been found as a contaminant in wheat, maize, and barley and livestock feeds.^3,4
