Description

1-Hydroxy-o-Methylsterigmatocystin is a structurally significant derivative of the sterigmatocystin family of mycotoxins. This compound is of primary interest as a key chemical reference standard and a crucial intermediate in mycotoxin research and analytical method development. It is essential for laboratories and institutions focused on food safety, toxicology, and the biosynthesis of fungal metabolites. Professionals in pharmaceutical development and environmental analysis also utilize this high-purity material for calibration and investigative studies.

Application

• Analytical Reference Standard: Primary use as a certified standard for the accurate quantification and identification of sterigmatocystin and related metabolites via HPLC, LC-MS, or TLC in food, feed, and environmental samples.
• Toxicological Research: Employed in studies investigating the metabolism, genotoxicity, and carcinogenic mechanisms of ochratoxin-related fungal toxins.
• Biosynthetic Pathway Studies: Serves as a critical intermediate for researching the aflatoxin and sterigmatocystin biosynthesis pathways in Aspergillus and other fungal species.
• Method Development & Validation: Used by quality control and contract research laboratories to develop, validate, and calibrate analytical methods for mycotoxin detection.
• Pharmaceutical Impurity Profiling: Acts as a potential impurity marker or starting material in the research of antifungal agents or toxin biosynthesis inhibitors.
