Description

Sterigmatocystin is a potent mycotoxin and a key biosynthetic precursor to aflatoxin B1, making it a critical compound for research and analytical applications. Its significance lies in its role as a model mutagen and carcinogen, essential for toxicological studies and the development of detection methods. This high-purity reference standard is primarily needed by analytical laboratories, food safety agencies, and pharmaceutical research institutions focused on mycotoxin analysis and metabolic pathway investigation.

Application

• Analytical Reference Standard: Primary use as a certified standard for the quantitative and qualitative analysis (e.g., HPLC, LC-MS/MS) of sterigmatocystin in food, feed, and environmental samples.
• Toxicological Research: Serves as a crucial reagent in studies investigating the mechanisms of mycotoxin-induced mutagenesis, carcinogenesis, and cellular toxicity.
• Method Development & Validation: Used by quality control laboratories to develop, calibrate, and validate analytical methods for mycotoxin detection to ensure regulatory compliance.
• Biochemical Studies: Employed in research exploring the fungal biosynthesis pathways of aflatoxins and related secondary metabolites.
• Food & Feed Safety Monitoring: Essential for laboratories monitoring contamination levels in commodities like grains, cheese, and spices to adhere to global safety standards.
• Pharmaceutical Impurity Profiling: Used in the analysis of natural product-derived pharmaceuticals where sterigmatocystin may be a potential contaminant.
