CAS 7220-81-7: Aflatoxin B2

Description:Aflatoxin B2 is a naturally occurring mycotoxin produced by certain molds, particularly Aspergillus species, such as Aspergillus flavus and Aspergillus parasiticus. It is classified as a potent carcinogen and is known for its toxic effects on both humans and animals. Aflatoxin B2 is a secondary metabolite that primarily contaminates agricultural products, especially grains, nuts, and seeds, under conditions of high humidity and temperature. The chemical structure of Aflatoxin B2 includes a fused bicyclic lactone ring system, contributing to its biological activity. It is soluble in organic solvents but has limited solubility in water. Due to its toxicity, Aflatoxin B2 is subject to strict regulatory limits in food and feed products. Exposure to this compound can lead to serious health issues, including liver damage and increased cancer risk. Monitoring and controlling aflatoxin levels in food supplies are critical for public health safety.
