Description

Ochratoxin A CAS NO 303-47-9 is a potent mycotoxin produced by certain species of Aspergillus and Penicillium fungi. This compound is of critical importance in food safety, agricultural, and pharmaceutical research due to its nephrotoxic, carcinogenic, and immunotoxic properties. It is primarily required by analytical laboratories, food safety agencies, and research institutions for use as a certified reference material in the development and validation of detection methods.

Application

• Analytical Reference Standard: Primary use as a high-purity certified reference material (CRM) for the calibration of analytical instruments and validation of testing protocols.
• Food and Feed Safety Testing: Essential for quantifying contamination levels in grains, coffee, wine, pork, and other susceptible commodities to ensure compliance with global regulatory limits.
• Research and Development: Used in toxicological studies to investigate mechanisms of toxicity, carcinogenicity, and organ-specific damage, particularly in the kidneys.
• Diagnostic Kit Development: Serves as a key antigen in the production of immunoassay kits (ELISA, lateral flow devices) for rapid on-site screening.
• Method Development and Proficiency Testing: Employed by testing laboratories to develop new HPLC, LC-MS/MS methods and to assess laboratory performance in inter-laboratory comparisons.
• Quality Control in Pharmaceutical Excipients: Monitoring for potential mycotoxin contamination in plant-derived excipients used in drug formulations.
