Description

Aflatoxin M4 is a hydroxylated metabolite of aflatoxin B1, a mycotoxin produced by certain Aspergillus species. This compound is of critical importance for research and analytical purposes, serving as a key reference standard in food safety and toxicology studies. It is primarily required by analytical laboratories, regulatory bodies, and research institutions involved in the detection, quantification, and toxicological assessment of mycotoxin contamination in agricultural commodities and food products.

Application

• Primary use as a certified reference standard for analytical method development and validation.
• Calibration and quality control in high-performance liquid chromatography (HPLC) and liquid chromatography-mass spectrometry (LC-MS/MS) analysis.
• Toxicological research to study the metabolism, bioavailability, and health effects of aflatoxins.
• Essential material for food safety laboratories monitoring compliance with global regulatory limits for mycotoxins.
• Use in the preparation of spiked samples for recovery studies and proficiency testing schemes.
• Supporting research in developing mitigation strategies for aflatoxin contamination in feed and food chains.
