Description

Cholic-2,2,4,4-D4 Acid CAS NO 116380-66-6 is a high-purity, deuterium-labeled derivative of cholic acid, a primary bile acid. This stable isotope-labeled compound is essential for use as an internal standard in quantitative mass spectrometry, ensuring unparalleled accuracy and reliability in analytical measurements. It is critically needed by researchers and quality control laboratories in the pharmaceutical, metabolomics, and clinical diagnostics industries for precise bioanalytical method development and validation.

Application

• Internal Standard for LC-MS/MS: Serves as a critical quantitative reference standard in liquid chromatography-tandem mass spectrometry for the analysis of endogenous bile acids.
• Metabolomics Research: Enables accurate profiling and quantification of bile acid pathways in studies of liver function, gut microbiome interactions, and metabolic diseases.
• Pharmaceutical Development: Used in pharmacokinetic and bioequivalence studies for drugs affecting bile acid metabolism or excreted via the biliary route.
• Clinical Diagnostics: Supports the development of high-precision diagnostic assays for conditions such as cholestasis, cirrhosis, and inborn errors of bile acid synthesis.
• Stable Isotope Tracing: Facilitates metabolic flux analysis in biochemical research to elucidate bile acid synthesis and enterohepatic circulation.
• Quality Control & Method Validation: Essential for validating analytical methods in compliance with regulatory guidelines (e.g., FDA, EMA) in GMP/GLP environments.
