Description

(-)-Citrinin-13C,D2 is a stable isotope-labeled analog of the mycotoxin Citrinin, specifically enriched with carbon-13 and deuterium. This compound is an essential internal standard for the accurate quantification and metabolic tracing of Citrinin in complex matrices using advanced analytical techniques. It is primarily required by analytical laboratories, food safety testing facilities, and research institutions engaged in mycotoxin analysis, toxicology studies, and method development for regulatory compliance.

Application

• Internal Standard for LC-MS/MS Analysis: Critical for precise quantification of Citrinin in food, feed, and biological samples, ensuring method accuracy and reproducibility.
• Metabolic Pathway Tracing: Used in pharmacokinetic and metabolic studies to investigate the absorption, distribution, metabolism, and excretion (ADME) of Citrinin.
• Method Development & Validation: Serves as a reference material for developing and validating new analytical methods in accordance with ISO, FDA, or EU regulations.
• Quality Control & Assurance: Employed in laboratory proficiency testing and as a calibrant to ensure the reliability of testing results across different platforms.
• Research on Mycotoxin Contamination: Facilitates studies on the occurrence, fate, and mitigation strategies for Citrinin in agricultural products.
