Description

o-Methylsterigmatocystin CAS NO 17878-69-2 is a methylated derivative of the mycotoxin sterigmatocystin, belonging to the aflatoxin precursor family. This compound is of significant interest in research and analytical chemistry as a critical reference standard and a key intermediate for toxicological studies. It is primarily required by professionals in pharmaceutical research, food safety laboratories, and environmental testing facilities for method development, calibration, and contamination analysis.

Application

• Analytical Reference Standard: Primary use for the calibration of analytical instruments (HPLC, LC-MS) in mycotoxin detection and quantification.
• Toxicology Research: Serves as a crucial intermediate or standard in studies investigating the biosynthesis, metabolism, and toxicological effects of aflatoxins.
• Food and Feed Safety Testing: Used in the development and validation of testing protocols to ensure compliance with global regulatory limits for mycotoxin contamination.
• Biochemical Research: Employed in enzymatic studies related to fungal secondary metabolism and the aflatoxin biosynthetic pathway.
• Quality Control Material: Acts as a certified reference material (CRM) for laboratory proficiency testing and internal quality assurance programs.
• Method Development: Essential for researchers developing new, sensitive analytical methods for the detection of sterigmatocystin and its derivatives in complex matrices.
