Description

3-Rac-Ochratoxin B tert-Butyl Ester is a chemically modified derivative of ochratoxin B, a mycotoxin, designed for analytical and research applications. This compound is of significant value as a high-purity reference standard and a crucial intermediate in the synthesis of labeled compounds for toxicological studies. It is primarily needed by analytical laboratories, research institutions, and pharmaceutical companies engaged in food safety testing, mycotoxin research, and the development of detection methods.

Application

• Analytical Reference Standard: Used for the calibration and validation of analytical instruments (HPLC, LC-MS/MS) in the quantification of ochratoxins.
• Metabolism and Toxicokinetic Studies: Serves as a precursor or intermediate in the synthesis of isotopically labeled (e.g., 13C, 2H) ochratoxin analogs for tracing studies.
• Method Development: Critical for developing and optimizing new chromatographic and mass spectrometric methods for mycotoxin analysis in complex matrices.
• Food and Feed Safety Research: Employed in research to understand ochratoxin contamination, stability, and the efficacy of detoxification processes.
• Biochemical Research: Used as a tool to study the biological activity, mechanism of action, and cellular interactions of ochratoxin derivatives.
• Quality Control & Assurance: Acts as a system suitability check and a critical component in proficiency testing schemes for laboratories.
