Description

(+/-)-Enterodiol-13C3 is a stable isotope-labeled analog of the mammalian lignan enterodiol, specifically enriched with three carbon-13 atoms. This compound serves as a critical internal standard for the precise quantification of enterodiol and its metabolites in complex biological matrices via mass spectrometry. It is essential for researchers and analytical laboratories in the pharmaceutical, nutraceutical, and clinical diagnostics sectors who require high-fidelity data for pharmacokinetic, metabolomic, and biomarker discovery studies.

Application

• Quantitative Mass Spectrometry: Used as an internal standard for the accurate LC-MS/MS or GC-MS analysis of enterodiol in plasma, serum, and urine.
• Pharmacokinetic & Metabolism Studies: Enables precise tracking of absorption, distribution, metabolism, and excretion (ADME) of dietary lignans and related pharmaceuticals.
• Clinical Biomarker Research: Facilitates the reliable measurement of enterodiol levels in studies investigating its role in hormone-related cancers, cardiovascular health, and gut microbiota interactions.
• Nutraceutical & Food Science: Supports the analysis of lignan content and bioavailability in functional foods, dietary supplements, and plant extracts.
• Method Development & Validation: Critical for developing, optimizing, and validating robust analytical methods in compliance with GLP and ISO 17025 standards.
