Description

Ochratoxin A CAS NO 1448049-50-0 is a potent mycotoxin produced by certain species of Aspergillus and Penicillium fungi. This compound is of critical importance for research, analytical, and quality control laboratories as a certified reference material (CRM) and analytical standard. It is essential for professionals in the food safety, agricultural, and pharmaceutical industries who require high-purity materials for method development, validation, and regulatory compliance testing.

Application

• Analytical Reference Standard: Primary use as a high-purity standard for the quantitative and qualitative analysis of ochratoxin A in various matrices via HPLC, LC-MS/MS, and ELISA techniques.
• Food and Feed Safety Testing: Critical for calibrating equipment and validating methods to monitor and control ochratoxin A contamination in grains, coffee, wine, spices, and animal feed to ensure compliance with global regulatory limits (e.g., EU, FDA).
• Toxicological Research: Used in studies investigating the nephrotoxic, hepatotoxic, immunotoxic, and carcinogenic effects of mycotoxins, supporting risk assessment and public health research.
• Method Development and Validation: Serves as a benchmark compound for developing new analytical protocols, assessing recovery rates, and establishing limits of detection (LOD) and quantification (LOQ).
• Quality Control (QC) and Proficiency Testing: Employed in internal QC programs and by external proficiency testing providers to ensure the accuracy and reliability of laboratory results.
• Diagnostic Kit Manufacturing: Used in the production and calibration of immunoassay-based rapid test kits for on-site screening of mycotoxin contamination.

Quality Control

Our Ochratoxin A is produced and handled under strict quality management protocols suitable for reference material applications. Each batch undergoes rigorous identity confirmation and purity analysis using advanced chromatographic and spectroscopic methods. Certificates of Analysis (COA) are provided, detailing batch-specific results for purity, related substances, and water content. Our quality system supports traceability and consistency, meeting the needs of ISO 17034 accredited reference material producers and analytical laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For long-term stability, store under inert atmosphere.
