Description

Ortho-Acetylsterigmatocystin is a chemically modified derivative of the mycotoxin sterigmatocystin, characterized by the acetylation of the ortho position on its xanthone core structure. This compound is of significant value as a high-purity reference standard and a critical intermediate in biochemical and toxicological research. It is primarily needed by analytical laboratories, research institutions, and pharmaceutical development teams focused on mycotoxin metabolism, biosynthesis pathway studies, and the development of detection methodologies.

Application

• Analytical Reference Standard: Used for the calibration and validation of analytical instruments (HPLC, LC-MS/MS) for accurate mycotoxin quantification.
• Biochemical Research: Serves as a key intermediate or substrate in studies exploring the enzymatic pathways of aflatoxin biosynthesis.
• Toxicology Studies: Employed in metabolic and toxicokinetic research to understand the biological effects and transformation of sterigmatocystin derivatives.
• Method Development: Critical for developing and optimizing new chromatographic or spectroscopic methods for the detection of complex fungal metabolites.
• Quality Control: Used as a certified reference material (CRM) in quality assurance protocols for food, feed, and agricultural product safety testing.
• Academic Research: A valuable tool for university laboratories investigating fungal secondary metabolism and mycotoxin chemistry.
