Description

Rubratoxin B is a significant mycotoxin produced by specific Penicillium and Aspergillus species. This compound is of critical importance in research and analytical fields for its role as a reference standard in food safety, toxicology, and mycology studies. It is primarily utilized by professionals in analytical laboratories, quality control departments, and research institutions focused on mycotoxin contamination and fungal metabolism.

Application

• Primary use as a certified analytical reference standard for the calibration of laboratory equipment.
• Critical component in the development and validation of analytical methods (e.g., HPLC, LC-MS/MS) for mycotoxin detection.
• Essential for toxicological research to study the effects, mechanisms, and metabolism of rubratoxins.
• Used in food and feed safety programs to ensure accurate quantification of contaminants.
• Valuable material for academic and institutional research in mycology and natural product chemistry.
• Employed in the production of quality control materials for laboratory proficiency testing.

Quality Control

Every batch of Rubratoxin B is produced and handled under strict quality management protocols to ensure identity, purity, and stability. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay purity and impurity profiles. Our quality systems are designed to support research and regulatory compliance, making this material suitable for demanding analytical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
