Description

Ochratoxin B is a mycotoxin and a structural analog of the more potent Ochratoxin A, differing by the absence of a chlorine atom. This compound is of significant interest in research and analytical chemistry as a critical reference standard and a key metabolite for studying mycotoxin contamination pathways. It is primarily utilized by professionals in food safety, toxicology, and analytical laboratories for method development, calibration, and quality control testing. The product is supplied as a high-purity material to ensure reliable and reproducible results in sensitive applications.

Application

• Analytical Reference Standard: Primary use for calibrating HPLC, LC-MS/MS, and other analytical instruments in food, feed, and biological sample testing.
• Toxicological Research: Used in studies to investigate the metabolism, toxicity, and biological effects of ochratoxins compared to Ochratoxin A.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for mycotoxin detection in compliance with global regulations.
• Quality Control (QC) Testing: Serves as a system suitability check and a control material in laboratory QC protocols to ensure analytical accuracy.
• Food & Feed Safety Monitoring: Employed in surveillance programs to assess and monitor the potential co-occurrence of Ochratoxin B with other mycotoxins in agricultural commodities.
• Production of Antibodies & Assay Kits: Used as a hapten or antigen in the development of immunoassays (ELISA) and lateral flow test kits for rapid screening.

Quality Control

Our Ochratoxin B is produced and handled under strict quality management protocols to ensure the highest standards of purity and consistency, suitable for use as a reference material. Each batch is characterized using advanced analytical techniques including HPLC and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation, and impurity profile is provided with every shipment to support your regulatory and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C. The product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability and purity. Allow the vial to equilibrate to room temperature before opening to prevent condensation.
