Description

Alternariol 3-Sulfate Ammonium Salt is a chemically defined ammonium salt derivative of the mycotoxin alternariol, a secondary metabolite produced by *Alternaria* fungi. This high-purity analytical standard is critical for accurate quantification and method validation in food safety and toxicology research. It is primarily utilized by analytical laboratories, research institutions, and quality control departments within the agricultural, food processing, and pharmaceutical industries.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration of HPLC, LC-MS/MS, and other analytical instrumentation.
• Food Safety Testing: Essential for developing and validating methods to detect and quantify alternariol and its metabolites in grains, fruits, vegetables, and processed foods.
• Toxicological Research: Used in studies investigating the metabolism, bioavailability, and toxicological effects of alternariol mycotoxins.
• Method Development & Validation: Serves as a key component in establishing ISO, AOAC, or other standardized testing protocols for mycotoxin analysis.
• Quality Control & Assurance: Employed by testing laboratories and manufacturers to ensure the accuracy and reliability of in-house mycotoxin screening programs.
• Regulatory Compliance: Supports compliance testing for international regulations governing mycotoxin levels in food and feed.
