Description

(+/-)-Catechin-[13C3] CAS NO 1261254-33-4 is a stable isotope-labeled analog of the natural polyphenol catechin, where three carbon atoms are replaced with the 13C isotope. This compound is essential as an internal standard for the precise quantification and metabolic tracing of catechin and its derivatives in complex biological matrices using advanced analytical techniques like LC-MS/MS. It is critically needed by researchers and quality control laboratories in the pharmaceutical, nutraceutical, and food science industries for method development, validation, and ensuring accurate analytical results.

Application

• Internal Standard for Mass Spectrometry (LC-MS/MS, GC-MS): Provides critical isotopic purity for accurate quantification of catechin in pharmacokinetic, bioavailability, and metabolomic studies.
• Drug Metabolism and Pharmacokinetics (DMPK) Research: Used to trace the absorption, distribution, metabolism, and excretion (ADME) pathways of catechin-based therapeutics and supplements.
• Nutraceutical and Dietary Supplement Analysis: Enables reliable quality control and standardization of products containing green tea extract, cocoa, or other catechin-rich ingredients.
• Biomarker Discovery and Validation: Facilitates the accurate measurement of catechin metabolites as potential biomarkers in clinical and nutritional research.
• Food and Beverage Science: Applied in the analysis of polyphenol content, stability, and authenticity in products like wine, chocolate, and fruit juices.
• Stable Isotope Labeling Studies: Serves as a tracer in plant biochemistry research to study flavonoid biosynthesis pathways.
