Description

Ochratoxin A-D5 is a stable isotope-labeled internal standard, specifically the deuterated form of the mycotoxin Ochratoxin A. This compound is essential for achieving high accuracy and precision in quantitative mass spectrometry-based analyses, as it corrects for matrix effects and instrumental variability. It is a critical reagent for analytical laboratories and research institutions focused on food safety, toxicology, and regulatory compliance, enabling reliable detection and quantification of Ochratoxin A in complex samples.

Application

• Quantitative Mass Spectrometry: Serves as an internal standard for LC-MS/MS and GC-MS methods to ensure accurate quantification of Ochratoxin A.
• Food and Feed Safety Testing: Used in the analysis of cereals, coffee, wine, spices, and animal feed for mycotoxin contamination to comply with global regulatory limits (e.g., EU, FDA).
• Clinical and Biomarker Research: Facilitates the precise measurement of Ochratoxin A and its metabolites in biological fluids (serum, urine) for exposure assessment and toxicokinetic studies.
• Method Development and Validation: A key component in establishing, optimizing, and validating new analytical protocols for Ochratoxin A detection.
• Quality Control and Proficiency Testing: Employed by reference material producers and testing laboratories to verify method performance and ensure data reliability.
• Environmental Monitoring: Applied in research analyzing fungal toxin presence in indoor environments (e.g., damp buildings) and agricultural settings.
