Description

Citrinin is a significant mycotoxin produced by several species of *Penicillium* and *Aspergillus* fungi. This compound is of critical importance in food safety, agricultural, and pharmaceutical research due to its nephrotoxic and potentially carcinogenic properties. It is primarily required by analytical laboratories, food safety agencies, and research institutions for use as a certified reference material in contamination testing, method development, and toxicological studies.

Application

• Analytical Reference Standard: Used as a high-purity certified standard for the accurate quantification of Citrinin in food, feed, and environmental samples via HPLC, LC-MS/MS, and ELISA methods.
• Food Safety Testing: Essential for calibrating equipment and validating analytical methods to monitor and control Citrinin contamination in grains (e.g., rice, wheat), fermented products, and dietary supplements.
• Toxicological Research: Employed in in-vitro and in-vivo studies to investigate the mechanisms of nephrotoxicity, genotoxicity, and potential synergistic effects with other mycotoxins like Ochratoxin A.
• Quality Control & Method Development: Serves as a critical component in the development, verification, and routine quality control of analytical protocols within testing laboratories.
• Regulatory Compliance: Supports compliance testing for international regulations and guidelines set by bodies like the FDA, EFSA, and Codex Alimentarius regarding mycotoxin limits in the food chain.
