Description

Ochratoxin CAS NO 37203-43-3 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, immunotoxic, and carcinogenic properties. It is primarily required by analytical laboratories, food and feed safety regulators, and research institutions for use as a certified reference material in contamination testing and toxicological studies.

Application

• Primary use as a certified reference standard (CRM) for the calibration of analytical instruments in food and feed safety testing.
• Critical component in the development and validation of analytical methods (e.g., HPLC, LC-MS/MS, ELISA) for mycotoxin detection.
• Essential for toxicological and pharmacological research to study its mechanisms of action and health impacts.
• Used in quality control laboratories to ensure the accuracy of test kits and assays designed for ochratoxin A detection.
• Supports regulatory compliance testing for global food safety standards in commodities like cereals, coffee, wine, and spices.
• Applied in stability studies and research on mycotoxin binding agents and decontamination processes.

Quality Control

Our Ochratoxin A is produced and handled under strict quality protocols suitable for reference material applications. Each batch undergoes rigorous identity confirmation and purity analysis using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) is provided, detailing assay purity, related substances, and confirmation of structure. Our quality system ensures traceability and compliance with relevant guidelines for high-purity chemical standards.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive); ensure the container is sealed under inert atmosphere or with desiccant to maintain stability and purity. Allow the vial to equilibrate to room temperature in a dry environment before opening to prevent condensation.
