Description

Altertoxin Iii CAS NO 105579-74-6 is a specific mycotoxin belonging to the altertoxin class, a group of secondary metabolites produced by certain *Alternaria* fungi. This compound is of significant interest in analytical and research settings for its role in food safety, toxicology studies, and environmental monitoring. It is primarily required by research institutions, analytical laboratories, and quality control departments within the agricultural, food processing, and pharmaceutical industries for use as a certified reference material or analytical standard.

Application

• Analytical Reference Standard: Serves as a high-purity calibrant for the accurate quantification of altertoxins in complex matrices using techniques like HPLC-MS/MS and LC-UV.
• Food Safety Research: Used in method development and validation studies to monitor and assess the contamination levels of *Alternaria* mycotoxins in grains, fruits, vegetables, and processed foods.
• Toxicological Studies: Employed in in-vitro and in-vivo research to investigate the metabolism, genotoxicity, and overall toxicological profile of altertoxins.
• Method Proficiency Testing: Acts as a key component in inter-laboratory comparison programs and quality assurance schemes to ensure analytical accuracy across testing facilities.
• Pharmaceutical Impurity Profiling: Utilized in research concerning fungal contamination of herbal medicines and raw materials to identify and quantify potential mycotoxin impurities.
• Environmental Monitoring: Applied in studies analyzing fungal toxins in environmental samples, such as dust from agricultural settings or contaminated soils.
